UPDATED: Compare Two Playlists v5.0
For macOS 11 and later only. Quickly compares the contents of any two playlists and displays the tracks that are common to both or the tracks in one playlist not contained by the other. Has tools to copy or move tracks from one playlist to another or delete common tracks from one or the other playlist. Can optionally create a text file report of these comparisons.
Free to try in Demo Mode: While in Demo Mode, several features will be disabled. An in-app purchase of a registration code will unlock the disabled features.

Latest version:
- Initial accommodation for macOS 12 Monterey
- Uses Split View to provide source playlists and work area; playlists can no longer be dragged from the Music app

UPDATED: Refresh Smart Playlists v3.4
For macOS 11 and later only. This script will "batch-refresh" the selected user-created Smart Playlists by removing the tracks they contain (if possible*) which obliges them to dynamically re-populate, ostensibly with different tracks.
*Note that tracks cannot be removed from a Smart Playlist which already contains every track of the library meeting its criteria--it would just re-populate with the same tracks. Smart Playlists with the "Limit to" and "Live updating" criteria in use are more likely to be "refreshable".

Latest version:
- Prevents errant selection of Playlist Folders
- Additional accommodations for macOS 11.3

UPDATED: Playlist Manager v4.0
For macOS 11 and later only. The Music app only allows one playlist to be selected at a time. This applet can perform common useful tasks on a multiple selection of playlists: playlist title renaming (add text, remove text, search and replace text) and duplicate, delete, export, move to Playlist Folder and merge playlists; change the View As and Sort By settings. (This script will require your permission to access "System Events" in order to run. Please see the Read Me RTFD doc.)

Latest version:
- Adds "Views" section
- Minor performance enhancements

UPDATED: Merge-Delete Playlists v6.2
For macOS 10.15 and later only. This script will allow you to merge the track contents of two or more playlists to a new or existing playlist or delete any number of playlists at once, including Smart, Genius, and Playlist Folder playlists. The merge feature will prevent the same tracks that may appear in different source playlists from being duplicated and has an option to delete original playlists. The delete feature only deletes playlists; tracks, of course, remain in the library.
This app is free to try full-featured in Demo Mode. In Demo Mode it will only process 5 playlists per launch. If you like it you can purchase a code for $1.99 which will unlock the Demo Mode restriction. Launch the app and click "Register…" in its File menu to make an in-app purchase.

UPDATED: Block Party! v4.3

Create a "Block Party!" playlist containing random Artists and a specific number of their randomly selected songs arranged in a row ("two-fers", "three-fers", and so on). You can restrict the size of the "Block Party!" playlist by Number of Artists or Duration in hours. Additionally, you can choose to use a particular Playlist as the source of tracks and include/exclude specific Genres.

View as Songs with Column Browser
One of the things that disappoints me about the Music app (and iTunes before) is that there is no way to set a default playlist View. Whenever a new playlist is created it will default to View as Playlist. I suppose this is fine and I don't dislike View as Playlist; it has its useful moments when a minimal look is desirable. But I prefer View as Songs because I do most of my tag editing and track sorting in that View under which much more information can be made visible.

For several years I've been pointing out the Keyboard Shortcut trick of assigning Shift-Command-S to View > as Songs and Shift-Command-P to View > as Playlist in order to quickly toggle the playlist View on the fly.

So I find myself typing Shift-Command-S followed by Command-B to turn on the Column Browser. A lot. Wonder if there's anything I can do about that...
