Do you like looking at album from music in your iTunes library? MusicPaper is a utility for displaying the currently playing track's artwork as the wallpaper on the current OS X desktop. Underneath the art, the details of the specific track (track title, album name, and artist name) are displayed if available.
How to use MusicPaper
When running, Music Paper will display an icon (a musical note) in the system status bar. From this menu you can enable or disable wallpaper updates, changing the font settings for the text, and quit the application.
