Just found an awesome new reference tool…LyricRat is a site that will take a snippet of lyrics that you give it, and then tell you the song, album, artist that the lyrics are from.
My favorite bit? If you tweet a lyric to @lyricrat, they will reply with the song and a link to the lyricrat site!
So very cool, and easy to use. Huge fan of services like this that provide a service in an almost completely transparent way: no sign up, no log in, no barriers.
