what exactly does poor beat selection have to do with being the best mc ever? if anything, it just adds to the declaration that he's the best ever, no? he's able to make songs with these "wack beats" still sound good because his lyrics completely overshadow and dominate the production, UNLIKE 95% of current rap where the beat and the hook is everything. nas isn't usually trying to make you dance and twerk and all that other shyt you nikkas be doin, with him it's more about listening than hearing, that doesn't mean awful production should be tolerated but still, Nas one of the only cats who doesn't need a crazy ass beat for the song to be crazy as hell.
