I've got some hard shit that isn't really super mainstream, but awesome nonetheless:

the bled - you know who's seatbelt
atreyu - right side of the bed
saosin - lost symphonies
nightwish - devil and the deep dark ocean
boy sets fire - after the eulogy
avenged sevenfold - trashed and scattered
pantera - cowboys from hell
slipknot - before i forget
thrice - paper tigers (awesome)
bullet for my valentine - suffocating under the words of sorrow
