Just listen to Brian Fallon of the Gaslight Anthem sing his version of I Do Not Hook Up. It gives me goosebumps every time I listen to it. His voice and his performance really gets under my skin.
I Do Not Hook Up was written by Katy Perry who never released the song. She gave it to Kelly Clarkson who recorded it in 2009. You can find her version here.
Brian Fallon completely transformed the song from a teen-pop number to an acoustic ballad. Mick Jagger was right. It's the singer that makes all the difference.
