Just to clear something up, screamo music sucks. Besides that there is deathcore, deathmetal, heavy metal, hardcore, etc. I know you don't care but I figured I would educate you because classifying it all as screamo is a little insulting, more ignorant. It's like calling rap and opera the same
No offense Violence but all those genres you mentioned are the same in most peoples eyes and ears haha.. It all sounds basically the same (screaming and incomprehensible guitar and drums).
