Nu-metal (Korn etc. etc.)
Thrashmetal (Slayer etc. etc.)
I dont like the ROAROAAAAAOROROAOROROROR like Grindcore :P i kinda hate it,! yes im attacking the grindcore lovers! its just Puking on a mic and farting on it and then loop it with hardcore drumming, Uber uber hardcore drumming, To finish the song off they Fap 2 times. And tadaaa! grindcore...
Edit: Im no metalhead, these two styles i just like, i mostly listen to Hiphop, rap, r&b and Pop; I listen to Metal while pvping.
