Sincronized with your LastFM profile, Lyrics Muse update your track lists, and makes possible to transcribe the lyrics of your charts. Obviously, it must be wrote for someone before... but for me, who try to listen music with some message and tell me something interesting, it is a great gadget. I don't know languages and most of the music i listen to it's in french, occitan, english, italian, euskara....
Actually there are around 7,300 artists, 1,200 albums and
36,000 tracks uploaded. Try it out, music is something more than rythm ;P
