Angerfist is super hardcore type stuff. It's called gabber music or hardcore techno and it's pretty brutal. Good songs: retaliate, street fighters, knock knock, incoming, sons of satan, etc. If that's too heavy/you don't like it, there's a less heavy type of gabber music called hardstyle. A well known hardstyle artist is headhunterz and some good songs are dragonborn, doomed, lessons in love, and others. I heard he switched up his style a bit so imma check him out again now too.
