This applet will create new Music track playlists based on each selected entry of a specified tag. That is, create individual playlists for each Artist, Album Artist, Album, Composer (and their "Sort" siblings), Genre, or Year.
For OS X 10.6 or later.
A good companion to this applet is Merge-Delete Playlists.
A new playlist will be created for each checkmarked entry and will contain Music tracks--in this case--whose artist tag is the same as the entry. The red-colored entries are already playlists.
List tracks not assigned to playlists
Make a text file listing Albums that have some/no tracks with artwork
Renumber order of selected tracks
Convert Roman numerals in selected tracks' name to upper case
Convert selected tracks and export the converted files to a new folder
Append user-entered text to beginning or ending of selected tag of each selected track
