Personally, I'm more on the Punk side... as Much as i like metal, there doesn't seem to be as much art/ concepts that coem along with music as a whole... I mean there are a few people that do that, but they're not really metal (like tool, and system of a down)...
By the way, when i say metal i mean the pure stuff, like slayer and co, not stuff that been influenced by metal, cos that would complicate the matter...
