Plugin which displays lyrics of the song that you are listening to.

Works on :
Winamp
Foobar 2000
Xmplay
Realplayer
Itunes
Yahoo Jukebox

You can both view the lyrics of the song and display them on your yahoo and/or gtalk status.
It's pretty smart on figuring out the correct lyrics and video, even if your song title is slightly wrong.
Note: Mute video sound, so it does not interfere with your music.
