Johnny Cash "Hurt" is one of the best performances ever. Cash is amazing and there is so much emotion in this song; I tear up every time I hear it. We miss you Johnny! He led a hard life for which we are all the better for knowing and learning from him. He and his music has left a lasting impression on all of us.
Trent Reznor of Nine Inch Nails wrote the amazing original (below), but Johnny put a life worth of pain behind it.
