Dimmu Borgir on Ozzfest??

What gets me is that people seem to think that just because Dimmu are playing on Ozzfest then metal is suddenly going to turn into a mainstream thing. I mean, c'mon, do you think your average mallcore fag is ready to listen to Cryptopsy, Disgorge or Mithras? The best metal will always be an "underground" thing, because the fact remains that most people cant appreciate it.
