Alright, we all know that Slipknot has some pretty slick sounding songs. Pummeling drums, gut-wrenching guitar growls, thundering bass and a singer's voice that will instill fear into uninitiated Slipknot listeners. "Psychosocial" is one of their songs that definitely gets your head bobbing; a classic Slipknot track. Well, some wiseacre thinks they have a great idea for mashup. Slipknot and Justin Bieber...yep. Give a listen after the break.
