All tracks which are linked to an Apple application will be added to the specified playlist. Playlist names follow the Apple App Playlist Naming Conventions. If the playlist does not exist it will be created. Tracks which are already in the playlist will not be added. You cannot add tracks to Genius or Smart playlists.
The supplied name string may contain any of the escape sequences described in Escape Sequences. If the name resolves to be empty at runtime, the application default as defined in Settings - Apple Apps - General will be used.
