I have to admit that I really didn't think much about Johnny Cash until I saw Walk the Line. I always thought he was cool, but didn't know much about his music. After watching the movie I decided to pick up a "best of" type album. I definitely feel like I picked the right one. Man, he had a great voice and you get to hear him at the top of his game at different points in his career. If you like Johnny Cash, or are a little curious about his music, this is a great CD set. I defnitely recommend it.
