Yeah DMX was signed to Columbia records years before he came out on Def Jam, when 2Pac was still around. I can't seethe embedded videos but he had a line that said "that nigga 2pac can suck my dick" and it was a version of Get at Me Dog...
I still bump It's Dark and Hell is Hot and Flesh of My Flesh, they got a different sound to them so you can't compare them to 2Pacs body of work
