I'd like to get more tables/desks/environnements to throw my albums on. For example, a computer desk with, at the top of the screen, the bottom of an iMac and, on the right side, the left 1/8 of an iMac mouse.
Instead of introducing more surfaces, how about just allowing us to import or export to playlists? As long as the imported playlists are limited to (or automatically truncated at) approx 12 or 24 albums for iPhone and iPad respectively, it shouldn't get too crowded on the desktop. For example, I have a smart playlist that holds my recent purchases - I'd love to be able to import that automatically for everyday listening and then swap it out temporaily for another playlist for a different mood.
