Music app
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
- Toggle playlist info visible

UPDATED: Remove From Other Playlists v3.0
A Correspondent recently divulged to me that his Music library contains over 5K Smart playlists. I just had to tell somebody.
It reminds me of an old Punch cartoon showing a rather ragged gentleman with a face full of bandaids and a very shabby looking growth of beard sitting at a table writing a letter: "Dear Sirs: I have used the same razor blade daily for seven months. Is this some kind of record?"
Anyway. It's good to keep yer library nice 'n' neat in my opinion. You can start with this:
Remove From Other Playlists will load, list and examine a selection of tracks from a selected playlist in the Music app and then display the other playlists that also contain them. The tracks can then be batch-removed from any one or more of these other playlists.

Latest version:
- Initial re-release

UPDATED: Show Me the Track Info v1.1
This script will display track info from the playing or selected track in a floating window that can be configured to show the information in a user-configured order. Eight sections within the window can be drag-arranged into their order of importance. The window can then re-sized to only display as much of the information as is necessary. Handy for quickly surveying tracks without having to click-click-click for the Music app's "Info Window".

Latest version:
- Adds guides to sections
- Minor UI adjustments
- Improved info gathering
- Setting to enable/disable clickable section to reveal file

UPDATED: Tracks Without Embedded Artwork v3.3
Universal, for macOS 11 and later only. MP3, AAC and ALAC audio files have the capability to store artwork image data internally as metadata, thus allowing artwork to "travel" with a file. This applet will examine the files of the selected tracks (or tracks in the selected playlist) for artwork metadata. Eligible audio tracks whose files are capable of embedding image data but do not contain artwork metadata will be copied to a new discrete Results playlist.

Latest version:
- Re-oriented scan settings
- Accomodations for macOS 26 Tahoe

UPDATED: Coverscope v2.8
Universal, for macOS 11 and later only. This applet will show both the assigned track artwork and the local file's metadata artwork (if any exists) for the selected track. The Track entry artwork well supports copy, paste and drags. Pasting or dragging image data immediately applies the image to the selected track's artwork and attempts to embed it. Additional tools can Embed or Apply artwork between track and file.

Latest version:
- Accommodations and adjustments for macOS 26 Tahoe

NEW: Who Da Album Artist v1.0
As you likely know, individual music tracks can each have their own individual artist tag. But there are situations when a single mega-artist is handy-like-a-handle for an album of tracks. Like "Various Artists" for compilation albums or "Ray Charles" if it's Ray with different artists on each track. That's why our Founding Fathers created the album artist tag.
Every discreet album in your collection should have an associated "album artist". It's what you'd see as the display artist on the cover or spine of a physical album, for example. Here in the digital future, where albums have been disintegrated into tracks, there is no "album"; the "album" information is born by the tracks it "contains" so the tracks can be re-integrated as an "album" in yer third-party devices there. Thus, the album artist tag is more like an "album tag", rather than a "track tag". Each track of an album should have the same text in its album artist tag. In fact, having mixed text in an album's tracks' album artist tags completely neutralizes the purpose of the mononymnic album artist tag. And some screwing up your music library royally is also nominally possible.
I thought I had album artist configurations handily and dandily in hand over the years. So I was recently in mid-to-high dudgeon after noticing a bunch of albums whose tracks had incorrect or inconsistent or missing album artist tags. CHAAAArrrristopher Columbus! Like I really wanna spend a lot of time going through my library looking for albums with problem album artist tags. So instead I spent what probably would have been the same amount of time making an app that would do the album artist wrangling for me.
Who Da Album Artist will scan your Music library and if it finds any album whose tracks' album artist tags are missing or inconsistent (more than one per album, for example), will give you the opportunity to enter the appropriate album artist and sort album artist tags.

Latest version:
- Initial release

UPDATED: Playlist XML Librarian v1.3
This applet will list the exported Playlist XML files collected in a specified folder with options to view, edit, search 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.

Latest version:
- UI adjustments and detailing; minimal Liquid Glass added
- Accepts Open'd and drag-and-dropped Playlist XMLs
- Description field displays popover for longer text
- Table displays Normalization value if present
- Adds "Send to Music app" and "Reveal Default Folder" buttons in main window
- Adds File and Remote Track Type counts to header display
- Handles :00.0 length URL entries properly
- Fixed issue with Filter
Frankly, I would rarely export a playlist as an XML file because traveling to the command to do it—buried in the Music app's File menu—always seemed like a long arduous journey for my mouse. That all changed when I assigned the keyboard shortcut Command-E to the File -> Library -> Export Playlist... menu command. Then I couldn't stop exporting playlists.

UPDATED: Playlist XML Viewer v2.0
Open (or drag-and-drop) and view the contents of a playlist XML file exported from the Music app in a conventional table layout. Includes options to play local files, send (import) the XML to the Music app, export a TXT, CSV or M3U version, copy info to clipboard and reveal existing files in the Finder. (Not for use with exported Library XML files.)
Also see Playlist XML Librarian which can manage a folder-full of exported Playist XML files.

Latest version:
- Adds audio player features
- Adds Open Recent Items subfolder

UPDATED: A Space Between v3.5
This stay-open applet will play each track in the selected playlist and will wait (you might say insert but that's technically incorrect) a user-set number of seconds between each. Play can commence at the "top" of the playlist or from a selected track and, optionally, in random track order.

Latest version:
- Fixed problem presenting donation panel
- Minor UI updates
More information for A Space Between v3.5 and download link is here.
UPDATED: Side Splitter v3.0
Side Splitter will allow you to configure a selection of tracks (presumably the tracks of a single particular album, although any tracks will do) like the sides of an analog LP. The script will then have the Music app play each "side" one at a time, with a few seconds of space between each track and slightly more space between sides (to emulate the time it would take to flip the record over).
The playback experience is, surprisingly, kinda remarkable, if I do say so myself. (Meanwhile, apparently there's some new Apple Music feature that forces tracks to seg even closer.)
You can get the track order for an album if you Search Discogs or Search Wikipedia.

Latest version:
- Accommodations for macOS 26 Tahoe
- Redesigned UI and concept
