AIMP Playlist Lock Not Working: How to Fix It

When the AIMP playlist lock is not working as expected, the first task is to identify what is actually changing. A locked playlist may still appear to change because AIMP is synchronizing it with a folder, Music Library query, another playlist, podcast feed, or remote source. The opposite problem can also occur: an apparently unlocked playlist may refuse manual edits because it is a smart playlist, its source file is read-only, Android lacks storage access, or the playlist has individual settings that override your expected behavior.

This guide focuses specifically on playlist locking in AIMP for Windows and Android. It begins with a small, reversible test and then works through playlist state, pre-image synchronization, file permissions, smart playlist limitations, plugins, skins, and profile problems. Follow the steps in order and stop as soon as the test behaves correctly. Changing unrelated playback, output, or decoder settings will not normally fix a playlist lock problem.

1. Confirm the Symptom With a Small Safe Test

Before changing your main playlists, determine whether the issue affects AIMP generally or only one playlist. A fresh manual playlist gives you a reliable control because it is not supposed to rebuild itself from a folder, library rule, feed, or remote playlist.

1.1 Create a Normal Manual Test Playlist

1. Create a new playlist in AIMP and give it a recognizable name such as Lock Test.
2. Add two or three local audio files that you know AIMP can already play.
3. Do not add an entire folder through a smart-playlist or synchronization command.
4. Do not assign a pre-image, source playlist, Music Library query, internet URL, podcast, or cloud folder.
5. Try adding, removing, and reordering one track while the playlist is unlocked.
6. Right-click the playlist tab on Windows and select the option that locks the playlist from changes. Depending on the interface language or skin, its wording may resemble Lock from changes.
7. Try the same add, remove, and reorder actions again.

Success means the unlocked test playlist accepts edits and the locked test playlist rejects content changes. If that happens, AIMP's basic lock function is working. Stop changing global settings and troubleshoot only the original playlist.

If the manual test playlist remains editable while locked, confirm that you locked the playlist itself rather than pinning, docking, or locking a window. The playlist lock protects playlist content. It does not necessarily prevent playlist tabs or interface windows from moving because those are separate skin and window-management behaviors.

1.2 Identify Exactly What Changes

Write down the action and result instead of describing the playlist as simply broken. Useful distinctions include:

• Tracks can still be manually added or removed after locking.
• Tracks return after you delete them.
• The track order changes after restarting AIMP.
• An unlocked playlist refuses dragging, deletion, or reordering.
• Titles or artwork change while the track list stays the same.
• A radio, podcast, cloud, or network playlist refreshes from its source.
• The lock appears enabled but is forgotten after AIMP closes.

These symptoms have different causes. Tracks returning after deletion usually points to source synchronization. Metadata changing is not necessarily a content-lock failure. A lock state that disappears after restart more often suggests that AIMP cannot save its profile or playlist data.

2. Check the Playlist Lock, Individual Settings, and Playlist Type

2.1 Verify the Lock on the Correct Playlist

On Windows, use the context menu for the affected playlist tab rather than a general toolbar or window menu. Select the playlist, right-click its tab, and inspect its individual commands. AIMP supports settings that apply to individual playlists, so one playlist can behave differently from another even when the application's general playlist preferences appear correct.

After changing the option, immediately test one harmless edit. If the lock is enabled, try moving a track or adding one local file. If the lock is disabled, try adding and then removing a test track. Success means the command now matches the playlist's behavior. Stop there unless the setting is lost after a restart.

2.2 Do Not Confuse Content Locking With Interface Locking

The content lock is intended to prevent changes such as adding or removing tracks and other playlist-editing operations. It is not a guarantee that playlist tabs, playlist groups, or separate skin windows cannot be repositioned. If your complaint is that a tab or window moves, examine the skin's docking, pinning, and layout controls instead of repeatedly toggling the playlist content lock.

To distinguish the two, attempt to remove a disposable track. If removal is blocked but the tab can still move, the playlist lock is functioning. No further playlist troubleshooting is required for that symptom.

2.3 Check for Automatic Sorting

A playlist can look as though it ignored the lock when its order changes automatically. Review the affected playlist's individual sorting settings and any option that reapplies the latest sort after content changes. Disable automatic sorting temporarily, put three test tracks in a memorable order, and restart or refresh the playlist.

Success means the order remains unchanged after automatic sorting is disabled. In that case, the lock was not the main cause. Leave sorting off or choose a sorting rule that matches how you want the playlist maintained.

3. Check for Pre-Image and Source Synchronization

AIMP can build smart playlists from folders, the Music Library, another playlist, podcasts, and other sources. AIMP documentation and developer guidance use the term pre-image for the source from which a playlist is built. When synchronization runs, the source can overwrite manual changes or make some manual operations unavailable.

3.1 Inspect the Playlist's Pre-Image

Open the affected playlist's individual settings or Playlist Manager and look for a pre-image, linked folder, Music Library source, or source playlist. Also look for synchronization options such as checking at startup, monitoring changes while AIMP runs, or reloading data from the pre-image.

If a pre-image exists, perform this controlled test:

1. Record the current source and synchronization settings so you can restore them.
2. Turn off automatic synchronization temporarily, if the playlist type permits it.
3. Make one harmless manual change.
4. Close and reopen the playlist or restart AIMP.
5. Check whether the manual change remains.

Success means the edit survives while synchronization is disabled. That confirms the source was rebuilding the playlist. Choose whether you want a source-controlled smart playlist or a manually curated playlist. Trying to use one playlist as both at the same time can produce recurring changes.

3.2 Understand Why Deleted Tracks Return

Suppose a playlist is linked to a music folder. You remove one song from the playlist, but the audio file remains in that folder. At the next synchronization, AIMP can discover the file again and restore it because the folder is the authoritative source.

The practical fixes are to exclude or change the source, adjust the smart-playlist selection rules, move the file outside the monitored location, or use a normal manual playlist. Do not keep deleting the same entry after every refresh. The repeated return is evidence that synchronization is working according to its source definition.

3.3 Check Music Library Rules and Rescan Behavior

A Music Library smart playlist is generated from database fields and selection rules. Manual deletion or reordering may be restricted because the results are supposed to match those rules. If an unwanted track appears, inspect the track's tags and the playlist's filtering criteria instead of treating the generated result like an ordinary list.

Use AIMP's file information or tag editor to inspect the fields used by the rule, such as artist, album, genre, rating, date, folder, or file path. Correct the relevant field, save it to the intended location, and then rescan or refresh the Music Library and smart playlist.

Success means the track enters, leaves, or moves within the generated results according to the corrected rule. Once the smart playlist matches its criteria, stop adjusting the content lock.

3.4 Test a Normal Playlist Before Blaming the Smart Playlist

If an unlocked smart playlist refuses manual deletion or reordering, copy a few of its tracks into a new normal manual playlist. If those tracks can be edited normally there, AIMP is not generally refusing edits. The limitation belongs to the smart playlist or its synchronization mode.

This test is particularly useful because smart playlists with automatic synchronization may intentionally limit manual deletion and ordering. If you need a fixed sequence for an event, album session, or personal queue, create a manual playlist rather than fighting a source-generated one.

4. Separate Content Changes From Tag and Artwork Updates

4.1 Determine Whether the Track List Actually Changed

A playlist lock does not necessarily freeze every piece of displayed information. AIMP may re-read titles, artists, album names, durations, or artwork from audio files, the Music Library, a stream, or external image files. The same file can remain in the same playlist position while its displayed label changes.

Compare file paths before and after the apparent change. On Windows, open file information for the entry and inspect its full path. If the path and playlist position are unchanged, but the title or cover differs, investigate metadata rather than playlist locking.

4.2 Check the Tag and Artwork Source

Use the tag editor or file information dialog to determine whether metadata comes from embedded tags, the Music Library database, a CUE sheet, a stream, or a nearby image file. If an external tag editor, organizer, converter, or cloud-sync application modifies the source file, AIMP may display the new information after rescanning.

For a safe test, copy one audio file to a temporary local folder, add it to a new manual playlist, and avoid editing its tags. If its display remains stable, the original source or metadata workflow caused the apparent change. Stop changing playlist lock settings and correct that workflow instead.

4.3 Review Converter and Renaming Options

If the issue began after converting, moving, or renaming files, check whether the resulting playlist points to new output files or whether old entries became unavailable. The converter can create files with different names and locations, while a monitored folder or Music Library rescan can then add those results to a smart playlist.

Review the converter's target directory, target filename preview, overwrite behavior, and any option that adds converted files to AIMP. Run a one-file conversion into a temporary folder. Success means only the expected output appears and the original playlist remains unchanged. If that test passes, correct the destination or playlist-addition option in the larger conversion job.

5. Check File, Profile, and Storage Permissions

5.1 Check for a Read-Only Playlist File on Windows

An unlocked playlist may refuse edits because AIMP can display the playlist file but cannot save changes to it. This can happen when the file or containing folder is read-only, stored in a protected location, controlled by another account, or synchronized from a source that restores an older copy.

1. Locate the playlist file or use AIMP's profile-folder link in settings when appropriate.
2. Close AIMP before changing file attributes.
3. Open the file or folder properties in Windows.
4. Confirm that your Windows account has permission to write and modify the file.
5. Make sure the playlist and relevant profile subfolder are not being forced into a read-only state.
6. Reopen AIMP, make one test edit, close AIMP normally, and open it again.

Success means the edit and lock state survive the restart. Stop changing permissions once AIMP can save normally. Do not grant broad access to unrelated system folders, and do not disable security software.

5.2 Save a Local Copy of a Remote or Imported Playlist

A playlist loaded from an internet radio directory, podcast source, HTTP address, WebDAV location, Samba share, or another remote service may not be directly writable. Credentials may allow reading and playback without permitting modification. The server may also replace local-looking changes during refresh.

Export or save a copy as a local playlist, then edit the local copy without synchronization. If the local copy works, the remote source, credentials, or source-controlled design is responsible. Keep the remote playlist for updates and the local playlist for manual curation.

5.3 Verify Android Storage Access

On Android, AIMP needs appropriate storage or music-and-audio access to read shared audio files. Saving playlists or deleting content can require additional access depending on the Android release, storage location, and document provider. A playlist located on removable storage may also become effectively read-only if the app has not been granted access to that location.

1. Open Android's application settings for AIMP.
2. Review permissions related to music, audio, files, or storage.
3. Grant only the access needed for the music and playlist location.
4. If Android presents a folder-selection screen, select the specific music or playlist folder.
5. Return to AIMP and test one edit in a small local playlist.

Success means the edit remains after leaving and reopening AIMP. If local playlists work but network or cloud playlists do not, move to network and credential checks rather than repeatedly changing Android permissions.

5.4 Check Network and Cloud Credentials

For WebDAV, Samba, FTP, cloud, or URL-based sources, verify that the account still has access and that the source is reachable. Read-only shares and expired credentials can allow cached content to appear while preventing updates. Refresh the source after correcting credentials, but do not delete the only copy of a playlist as a test.

Success means AIMP can reload the source without an authorization or access error. Remember that successful source access does not make a remote smart playlist manually editable. Save a separate local playlist if you need independent changes.

6. Rule Out Plugins, Skins, and Device Controls

6.1 Switch Temporarily to a Standard Skin

A skin controls how commands are presented and can make a menu item, state indicator, or window lock easy to misinterpret. Switch temporarily to a standard AIMP skin, locate the playlist tab's context menu, and repeat the manual test.

If locking works with the standard skin, the original skin likely hid the command, displayed its state unclearly, or exposed a different lock related to window layout. You can return to the custom skin after identifying the correct playlist command.

6.2 Disable Playlist-Related Plugins for One Test

A plugin that imports feeds, updates radio entries, manages queues, reads external playlists, or modifies playlist content can create changes that appear to bypass locking. Disable only the suspected plugin, restart AIMP, and repeat the test in a copied playlist.

Success means the copied playlist remains stable without the plugin. Re-enable other plugins and keep the suspected one disabled until you can update or reconfigure it. There is no need to remove audio decoders, install codec packs, or disable security tools for a playlist-lock symptom.

6.3 Exclude Playback Controls That Do Not Edit Playlists

Bluetooth buttons, headset controls, Android Auto, media keys, exclusive audio modes, and output-device settings normally control playback rather than the saved playlist. They may skip tracks or alter the queue, which can look like the playlist order changed even when the underlying list did not.

Close and reopen the playlist, then compare its saved order. If only the current playback sequence changed, inspect shuffle, queue, and device-control behavior. Do not change audio output mode unless the problem is playback itself rather than playlist content.

7. Use AIMP's Diagnostic Tools Without Risking Your Playlists

7.1 Check Playlist Manager and File Information

Playlist Manager helps identify inactive playlists, linked sources, and individual playlist configuration. File information helps confirm that two entries with similar titles are actually the same file. Use these tools before deleting duplicates or rebuilding a large library.

For each suspicious entry, compare its full path, source, and playlist type. Success means you can explain whether AIMP restored the same source file, added a converted copy, or displayed a remote entry with updated metadata.

7.2 Refresh Only When the Playlist Is Supposed to Synchronize

The command to reload data from the pre-image is appropriate for a smart playlist. It is not a repair command for a normal manual playlist. Running it on a source-linked playlist deliberately rebuilds content and may undo manual-looking changes.

Use a Music Library rescan when library data is stale, a tag rescan when displayed metadata is stale, and a pre-image reload when the generated playlist must match its source. Select the narrowest operation that matches the symptom.

7.3 Use Debug Mode for a Repeatable Save Failure

If AIMP consistently loses the lock state or playlist edits after closing, diagnostic logging may reveal a profile or file-write error. On Windows, AIMP support guidance may ask you to start the application with the /DEBUG command-line switch, reproduce the issue, open the profile folder through settings, and inspect or provide the generated AIMP log.

Use debug mode only long enough to reproduce the problem. Avoid posting logs publicly before checking them for personal folder names, network addresses, or account details. If the log points to an inaccessible playlist or profile path, correct that path or permission and retest once.

8. Run a Clean Temporary Test Before Reinstalling

Reinstallation is rarely the best first response because the existing profile, playlists, plugins, and settings may remain in place. A temporary clean environment is more informative and avoids destroying useful data.

8.1 Back Up Before Changing the Profile

Use AIMP's settings to locate its profile folder, then close AIMP and make a backup copy. Also export or copy any important manual playlists. Do not delete your only playlist files, Music Library database, or plugin configuration while troubleshooting.

8.2 Create an Isolated Test

Use a separate portable or temporary AIMP setup when available, without copying custom plugins, skins, or old playlists into it. Create one manual playlist with three local files and test locked and unlocked behavior.

• If the clean test works, the installed player is probably fine. Investigate the original profile, plugin, skin, playlist source, or file permission.
• If the clean test fails with a normal local playlist, record the exact steps and consult AIMP support with the debug log and system details.
• If only the original playlist fails, preserve it and test an exported copy before rebuilding anything.

Stop when you have isolated the failure to one component. Do not reinstall, reset the library, replace every playlist, and remove all plugins simultaneously because that destroys the evidence needed to identify the cause.

9. Quick Fix Checklist

• Create a normal manual playlist and confirm that locking blocks content edits.
• Right-click the correct playlist tab and use its individual lock-from-changes option.
• Do not confuse playlist content locking with tab, window, docking, or skin locking.
• Check whether the playlist has a folder, Music Library, playlist, podcast, or URL pre-image.
• Pause automatic source synchronization and repeat one harmless edit.
• Use a manual playlist when you need fixed order and unrestricted editing.
• Check individual automatic-sorting settings when only track order changes.
• Compare file paths when only titles, tags, or artwork appear to change.
• Confirm that the playlist file and AIMP profile folder are writable.
• On Android, verify access to the exact storage location containing the playlist.
• Save a local copy when a remote playlist or share is read-only.
• Test with a standard skin and without the suspected playlist-related plugin.
• Run a clean temporary profile or portable test before reinstalling.
• Use debug mode for a repeatable failure to save playlist state.

10. Frequently Asked Questions

10.1 Why Does a Locked AIMP Playlist Still Add Tracks?

The playlist may be linked to a pre-image such as a folder, Music Library query, source playlist, feed, or remote URL. Synchronization can rebuild content from that source. Temporarily disable synchronization or copy the tracks to a normal manual playlist. If the manual playlist stays unchanged while locked, the lock works and the linked source caused the additions.

10.2 Why Do Deleted Songs Return to the Playlist?

The files probably still match the smart playlist's source or Music Library rules. Remove or exclude them from the source, adjust the selection criteria, correct the relevant tags, or use a manual playlist. Deleting generated entries without changing their source usually provides only a temporary result.

10.3 Why Can I Not Edit an Unlocked Playlist?

It may be a smart playlist whose content is controlled by synchronization, or its playlist file may be read-only. Test the same tracks in a new manual playlist. If the new playlist accepts edits, inspect the original playlist's pre-image and individual settings. If no playlists save edits, check profile and storage permissions.

10.4 Does Playlist Locking Freeze Tags and Album Art?

Not necessarily. The lock protects playlist changes, but AIMP may still re-read metadata or artwork from files, the Music Library, streams, or nearby image files. Compare the file path and playlist position. If those remain unchanged, troubleshoot the metadata source rather than the lock.

10.5 Can I Manually Reorder a Smart Playlist?

Some smart playlist modes restrict manual ordering or reapply their configured sorting after synchronization. If you need a permanent custom sequence, copy the desired tracks into a normal manual playlist. Success means your chosen order remains after restarting AIMP without a source reload.

10.6 Should I Reinstall AIMP to Fix Playlist Locking?

Not before testing a clean temporary profile or portable setup. If a clean manual playlist locks correctly, reinstalling the application is unlikely to fix the original source, permissions, plugin, skin, or profile problem. Back up your data, isolate the failing component, and change only that component.
