Desktop Covers is the Mac app that frees your iTunes album artwork by showing the currently playing music’s artwork on your desktop’s background and dock icon.
As well as the track’s cover artwork, the name, artist and album information is also shown on the desktop, including details of the next song (if the playlist is not in shuffle mode).
The dock icon changes to the cover art of the playing track, so that at a glance you known which album is playing.
There is an option to superimpose the album artwork over your existing background image (with the additional options to darken and blur the background image).
By default when you quit the application it leaves the last playing album artwork as your background, but this feature can be switched off in the preferences allowing the original desktop background to be restored.
Those with two screens can use the application's preferences to display the album artwork on the main screen, a second screen or both screens.
