I cried when I heard the news this morning. Johnny Cash was an amazing person. He was supposed to start work on his next album soon... the music world will never be the same without him. But he's got to be so happy to be back together with June (his wife).
Everybody should take a few minutes to watch the video for his cover of Hurt. You can find it at launch.yahoo.com, among other places. It's a beautiful, albeit sad, tribute to his life.
We'll miss you, Mr. Cash.
