As much as Im not a fan of him, Eminem was probably the best freestyle battler ever. I seen some footage of his battles he was fucking ridiculous in battles.
I seen some shit where he was battling cats and was clowning them on what they were wearing and shit so i know that wasn't written. I can tell by listening to what's being said. I ain't seen the video you're talking about.
