Music app
UPDATED: Remove Duplicate Tracks from Playlist v2.1
Tracks may have been dragged/added/copied to a user playlist two or more times—defying the Music app's caution about adding them—and now each of them appears multiple times in the playlist. This script will remove all but one of these kind of duplicate tracks from a selected playlist. (This does not have anything to do with duplicate files that each have an individual track entry in the Music library.)
Also see Remove From Other Playlists which does what it says.

Latest version:
- UI rebuild
- Maintenance and minor fixes

UPDATED: Copy Tracks to Multiple Playlists v6.3
This applet will copy the selected tracks to one or more chosen playlists--or move them, after which they will be removed from the source playlist (if possible; tracks cannot be removed from dynamically populated playlists).
Also see Remove From Other Playlists.

Latest version:
- Fixed regressions
- UI rebuild
- Minor maintenance

UPDATED: Lyrics Tag Viewer v1.2
View and edit a selected track's Custom Lyrics tag in a non-modal window, which, unlike a track's Info panel, will not block keyboard and mouse activity in the Music app's interface.

Whereas the Comments tag can only accept about 250 text characters, the "Custom Lyrics" tag can hold a lot of text. And I mean a lot of text. Custom Lyrics text will also get written to a track's file as metadata. So it's an ideal place to store information about an album. Especially if you're not interested in storing lyrics there.
I got in the habit of using the Lyrics tag of the first track of an album to store liner-note-caliber text snippets about the album. Or actual liner notes if they are available. The screenshot above shows some text I copied from the album's Wikipedia entry. In any case, I know that if an album has any info it'll be in track 1's Lyrics.
But a track's Show Info displays a modal window which prevents doing anything else with the Music app while it's open. So I use Lyrics Tag Viewer to display the lyrics or liner notes or what have you while an album is playing but without blocking access to Music.

UPDATED: Playlist XML Librarian v2.1
The original AppleScript version of Playlist XML Librarian had a search function but I didn't like it much. So I decided not to include it in the v2.0 rebuild until I figured out a better way to do it. Well, I went ahead and did that for v2.1.

Playlist XML Librarian v2.1 will list the exported Playlist XML files collected in a specified folder with options to view, edit and send (import) them to the Music app. Makes it easy to maintain an organized stockpile of exported Playlist XMLs to reduce the number of onboard Music playlists.
Also see Playlist XML Viewer which can display and play a single selected local Playlist XML file drag-and-dropped or chosen. For handling exported library XML files, see Library XML Track Viewer
Latest version:
- Adds search feature; searches XML collection for playlist XMLs with track entries whose Title, Artist, Album or Composer tag matches entered search text.
- v2.0 (jun 3 2026):
- Outgrew AppleScript, is now a full-fledged Xcode app
- Overall speed boost
- Checks each XML file for appearance in the Music app as status
- Sort playlist XML list by name, date, track count, playlist kind and status
- Additional Settings to configure status indexing and display
- Description overspill appears in popover
- Toggle playlist info visible

UPDATED: File Renamer v5.3
Here's a utility that's been waiting for a few fixes and I finally got around to them.
File Renamer will rename the files of the selected tracks (or the files of the tracks in the selected playlist) using a substitution pattern that you formulate from the tracks' tag data. Optionally, export a copy of the files to a chosen location and rename the files in that location.
Works optimally for "in place" option with Music app's "Keep Media folder organized" un-checked.

Latest version:
- Fixed some regression issues impeding operation
- Minor UI adjustments

UPDATED: Quick Convert v5.8
Convert all or just the selected tracks of the selected Playlist using your choice of available encoders, restoring your Settings-set encoder afterwards.
Additionally, you can:
- Choose to delete and/or Trash the original tracks and/or files
- Copy all converted tracks to a playlist

Latest version:
- Minor UI updates

NEW: Library XML Track Viewer v1.0
I guess every time I opened an exported Music (or iTunes) XML file in BBEdit I said to myself, "You know, it'd be easy to write an app that made lookin' at this thing easier." Then I'd forget about it. And then the next time, I'd say to myself, "You know, it'd be easy to write an app that made lookin' at this thing easier." And so on.
This sort of thing went on for about twenty-five years.
Well it stops today. Examine just the track entry content of any Library XML file exported from the Music app (or older iTunes) in a familiar list view. The list of items can be narrowed by entering text in the Filter field. Basic information from a selecton of items can be copied to the clipboard.
(For handling exported playlist XML files, see Playlist XML Viewer and Playlist XML Librarian.)

Latest version:
- Initial release

UPDATED: List MIAs v6.6
Universal, for macOS 11 and later only. This applet checks your Media library for missing and presumed dead tracks—those tracks that have become disassociated from their file and which are listed with a "!"—and can delete them from the Music app or create a text file listing these tracks by last known File Path, Title, Artist and Album, which you can view using TextEdit.
Also see Super Remove Dead Tracks and Media Folder Files Not Added.

Latest version:
- General maintenance, UI update
- Fixes unusual issue with locating track for reveal

UPDATED: Needle Drop v7.8
Needle Drop plays each track in the selected Music playlist for a set time interval optionally starting at a set number of seconds into each track, beginning with the selected track. Handy for 'scoping playlists.
Needle Drop will work best on tracks that have local files. Un-cached tracks streamed from the cloud may upset timing while audio is being downloaded.

Latest version:
- Fixed issue causing crash on engage
- Updates UI Scripting to correct an issue that may have prevented operation
- General maintenance

UPDATED: Playlist XML Librarian v2.0
I've suspected for years that there would come a time when I'd want one of my AppleScript dinguses to grow up into an Xcode app. You can only do so much with a single thread. I've been using Playlist XML Librarian pretty regularly and the AppleScript incarnation just wasn't able to gimme what I need.
Playlist XML Librarian v2.0 will list the exported Playlist XML files collected in a specified folder with options to view, edit and send (import) them to the Music app. Makes it easy to maintain an organized stockpile of exported Playlist XMLs to reduce the number of onboard Music playlists.
Also see Playlist XML Viewer which can display and play a single selected local Playlist XML file drag-and-dropped or chosen.

Latest version:
- Outgrew AppleScript, is now a full-fledged Xcode app
- Overall speed boost
- Checks each XML file for appearance in the Music app as status
- Sort playlist XML list by name, date, track count, playlist kind and status
- Additional Settings to configure status indexing and display
- Description overspill appears in popover
