Only remember a few lyrics, but can't think of the song's name?
Go to Lyricrat, type them in, and LyricRat will tell you the song.
Or twitter the lyrics to @LyricRat on Twitter, and it will respond with the song title.
It does pretty well even if you don't know the lyrics. "Wrapped up like a douche, another rubber in the night" will probably still get you "Blinded By The Light"
