I currently use a little program called GimmeSomeTune, which displays song lyrics, and information on the desktop. It used to show artwork and automatically pull lyrics, but the development of the program has ground to a halt with the release of OS X Lion. It does other things like hotkeys and last.fm, but I mainly use it for its ability to display lyrics and song information. As of 10.7 Lion, the thumbnail artwork is broken. What do you use to display song lyrics and song information?
