I agree 100% with the original comment about more accessability to artists. The reason I got into bands like Suffocation and Napalm Death so late was because when I was a teenager in the 1990's there was no internet. So to hear a new band you either had to do it through the grapevine, at a show or take a gamble. I was never willing to shell out $20 on a CD of a band that I wasn't even sure I'd like. Now if I'm interested I have so many avenues to get a sample.
And the whole downfall of the music industry has hurt all artists but metal bands never made money anyways, so it hasn't changed that much for them. Sure, Celine Dion is suffering but Carcass are scraping by just like they always did.
