Question: Three types of standard playlist icons (symbols)
Look at this - a screenshot of the sidebar in iTunes 188.8.131.52 on High Sierra:
There are two smart playlists and 3 standard playlists.
The symbol for 'Playlist' is familiar. But what do the other two symbols mean - the one with 4 lines ('now') and the other with 4 lines and a downward arrow ('Purchased')?
