This is not saying that you shouldn't listen to bands who wear corpse paint and use blastbeats (namely, generic black metal bands). What he's saying is that these generic black metal bands have come to be what constitutes what is 'metal' for a lot of people these days, and it's reached the point where all of these bands are wearing corpse paint and using blastbeats simply because that's what is metal to them, they don't understand it any other way. I could elaborate further but it's a really simple and stupid point to argue over. If you don't like the music then whatever.
