There are over a million billion resources out there on heavy metal and death metal, but very little of it is of quality. The commercial stuff exists to sell you whatever the labels have cooked up as their latest; the underground stuff is designed to find novelty in trivial things so you have something new to discuss with your hipster loser friends (and don't let anyone fool you: hipsters are cleverly disguised losers and they wreck genres by freeloading on hype with imitation). Only a few sites exist of any importance, and those are created by fanatics who love the music and believe in it in a way that no hipster or mindless consumer ever could.
