What makes the two go so well together?

I honestly have no clue why (almost) everyone on the net listens to Metal. I'm not saying it's bad music, I'm just wondering why it's the most popular genre on the internet.
And I'm not really looking for "metal is da best" answers, I'm just interested in hearing why you listen to metal. I, myself, don't really listen to metal at all, apart from an occasional song I like (that rarely happens >_>), I'm more of a trance/dance type of person :v
