I love the different styles of Cash's version, nine inch nails, and the Eric Whitacre choral version. They all bring out different parts of the text, and the comparison is fascinating.
I just can't shake the feeling that the only way Johnny Cash COULD find any relevancy was to cover am edgy song. The Johnny Cash version just sounds like an old man trying to be cool, it's really lame.
Holy cow, that one brain cell you have is working overtime. How about you lookup the history of that album, which was produced by the legendary producer Rick Rubin.
