a song

Today, I hitched a ride from Rachel. Her CD player was playing a soundtrack of House, M.D. There was a song in it I really liked, but I don't know what it is. It sounds like a man, but sounds like a woman with a deep voice. There were high notes and low notes, and a very special bridge with a chorus of sounds with at least a string quartet. The genre could have been alternative/indie. It could have been used on a very emo episode of House. Does anybody know what song I'm talking about?
