depends on how you mean it..hardcore can be anything..and actually there is a "HARDCORE" rap category..but you are right rock is considerably more hardcore than rap..
three 6 mafia was good back in the day but now there just like every other rapper or rap group (sell outs).I have all of there cds and if you listen to all of them they all are very similar talking about money,pussy, and weed.That shit just doesnt do it for me anymore i need something real and uplifting like common,kanye,ludacris.But there best cd yet is still 66,661 when the smoke clears,man those beats were hard.
IMORTAL TECHNIQUE...thats what i consider hardcore rap!...i myself though am a hxc man! if theres any hardcore metal fans out there check out some of there bands!.. LIGEIA...MY BITTER END...AS I LAY DYING...UNEARTH..LAMB OF GOD....THE DEVIL WEARS PRADA...THE ACACIA STRAIN...i could go on and on...but those r some good bands!
