For macOS 10.12 and later only. This script will copy all the tracks in a selected Playlist Folder to a new "plain" playlist, essentially duplicating the tracks as viewed when the Playlist Folder is selected. Optionally, after copying, the selected source Playlist Folder can be deleted along with the playlists it contains (of course, the tracks remain in your library). Note that if any "dead" tracks exist at any level of the selected Playlist Folder the script will fail.
Enter a name for the new playlist, and, optionally, delete the selected source Playlist Folder and its playlists and any sub-Playlist Folders.
