Yeah, I'll be friends with any metalhead, but I'm sure I'd have more in common with a death, black, thrash, or grindcore fan than the others. I only have 2 friends into extreme metal and they're only into Norwegian black metal 2nd wave like Burzum, Darkthrone, Immortal, Satyricon, Emperor, and Dark Funeral(I know they're Swdedish) and that's all their bands and they don't listen to later Emperor and only know 3 swongs of Dark Funeral and a few by Darkthrone and every Burzum song ever made, and Mother North and a few newer Satyricon songs, so they're not as deep into BM like many people on this forum. Their musical tastes are classic rock and mainstream rock music and one of them is into emo more than black metal now. I still have no death friends.
