As a founding member of Black Sabbath, Ozzy Osbourne helped invent heavy metal, but that doesn't mean he feels any particular fondness for it as a genre.

"I have never ever ever been able to attach myself to the word 'heavy metal' — it has no musical connotations," Osbourne admitted during a recent interview with CNN (you can see the video above). "If it was heavy rock, I could get that," he argued, but as he sees it, the music has gone through a lot of changes over the years and grown to include a lot of artists he feels distant from creatively.

"The '70s was kind of like a bluesy thing, the '80s was kind of bubblegum-frosted hair, multicolored clothes and the '90s was kind of grungy," Osbourne explained. "People come up to me and say, 'Your Sabbath work was a big influence on me.' I could go, 'Oh, yeah, I can see that.' But other bands ... what part of that is inspired by us? Some of it is just angry people screaming down a microphone."

Dismissive statements aside, it sounds like it's nothing personal; in fact, Osbourne admitted he was fairly taken aback when Rick Rubin, who produced Sabbath's new '13' record, told the band he wanted them to go back to the beginning in terms of sound.

"I think it must be over 30 or 40 years since I listened to the first album, because, you know, you move on and you challenge yourself," he mused. "It's like asking the Beatles to go back to 'Please Please Me,' and they would have gone, 'What?'"
