Neither one of those Niggaz (Nas) or (Jay-Z) are nor will they ever be the best to ever do it. That title belongs to some M.C. that maybe y'all mighta heard of, i think his name was sometin' like 2Pac, or sometin' like that.
As far as now, Nas is definately right up there. And jigga can suck my nutz.
