The players that are compatible with CoverGloobus are Banshee, Spotify, Rythmbox, Amarok2, Exaile, Exaile3, Listen, QuodLibet, Audacious, MPD and Songbird. Any song that is played with these programs will be automatically sought in Amazon, as the same time that the application tries to find the lyrics in the Wikilyrics and Lyricsfly. On the other hand, if you want to learn how to play all the songs, the software can also search for the score in Ultimate Guitar.
The interface with which this software shows the covers and other information is totally customizable, allowing to modify every last detail thanks to the fact that it is designed in XML.
To sum up, this software is highly advisable, and will surely brighten up your desktop somewhat.
