I couldn't have said it better myself...Eddie Van Halen wrote:...It's like asking which guitarist is better. Nobody is better than anybody. Every player is their own person. Music is not the Olympics. It's not a sport; it's a form of expression. There is no such thing as bad music. There may be music that you don't personally like, but if you don't like it, don't listen to it and shut the fuck up! Don't listen to it and complain about it. There's lot's of music I don't care for, but you can't say it's bad. That's subjective.
Interestingly, he also equates the genius of the opening riff to Black Sabbath's Into the Void with Beethoven's 5th symphony. Sober Ed is an interesting guy.
