It's important to realize that everybody who went into country music, and most everybody who went into rock and roll in the '50s, they had no more goal than a hit on the jukebox. Johnny Cash, from the very beginning, had a goal that he wanted to make music that lifted people's spirits.
I don't want to be the cranky old guy, but a lot of critics are too forgiving of mediocre artists. When you see these 'American Idol' people on the cover of 'Rolling Stone' being written about as serious artists, there's something wrong with that. You can erase them from the history of rock n' roll, and you wouldn't notice.
