I'm gonna direct you to some blogs that post about heavy music, but not necessarily the stuff your looking for.
icoulddietomorrow: Probably my favorite music blog, lots of oldschool hardcore, black metal, thrash, and other random stuff the dude who writes it likes (pop, hip-hip, indie, etc.)
Chainsaw Justice: Doesn't update too much anymore, but great spot to go to for black metal, death metal, and grindcore.
creation is a curse: Run by this kid who posts on another board I post on, lots of 90's type hardcore, probably lots of stuff you'd be into
Behold ...the Blogtopus: Metal.
Cosmic Hearse: More heavy, angry music.
Check those out, download some stuff, and for the love of real music, don't fucking listen to Attack Attack.
