I see your points man. Kumbe ukiachaga zile fujo, unakuwa makini arif.
Anyway, "probably none of it all coulda been as big without Dre" in a sense that, N.W.A stood as big after Dre. Death Row grew even bigger after Dre. The Eminems, Kendricks, Snoops were real talents waiting to blow up even without Dre. The headphones turned out that big, coz they were the new thang in the game, so maybe they coulda grown even bigger if Jimmy gave them to Em or 50 before Dre.
The arguments that are put out there to credit Dre, which I think are a little exaggerated, could as well be said for others involved and fit them perfectly. Cube & Eazy roles in N.W.A. Suge's in Death Row, et cetera et cetera.
