Every time I listen to the whole album instead of just the handful I rated up on my playlist, I find that I like the album more and more.
The other two "new" Johnny Cash albums American Recordings and American VI: Ain't No Grave didn't stand out for me on my first listening, which didn't surprise me very much. But The Man Comes Around... If you've ever liked anything that Johnny Cash ever did, you need to get this album. Lots of covers, but he does it right I think.
Maybe I'm getting old and I've lost too many friends and family members before their time, but Cash is one of those artists that resonates with me. Anyone who groks the definition of the word "resonates" ought to understand that.
