This is my dedicated screen for music, computer infos and applications' shortlinks. (i'm running on tri-screen)
I mix a customized CD Art Display partialy covering my desktop, which use Objectdock icons.
CDA displays artists pictures and the movie/tv serie/anime related ones (all manually added), if there is one, then a discrete progress bar at the top of the screen.
MB always displays the lyrics and track info. I switch to the main windows with a keyboard shortcut to set my playlists.
