What's with all the album art? I stopped caring about album art when I switched from LPs to CDs. (Oops I dated myself.)
On the iPad, If you're looking at playlists, you can't tell if you're looking at a folder with playlists in it, or just a playlist.
In the list view, the button to go back a view is on the top left. If you're looking at the playing song's album cover, the button to go back is on the bottom right?
If you're in the list view in a non-genius playlist and hit the genius button for the song playing, nothing appears to happen, except the little speaker icon next to the playing song goes away. You're actually now playing the genius playlist, but you have to hunt back through the playlists to find it. If you already in a genius playlist and create a new one, the list view refreshes.
