Would D.J. Quik have the same sound he has without Dr. Dre? Would Above the Law have blown up if Dre wasn't around? Dre's beats don't amaze me, but his shit appeals to people and he can put anyone on the map (gangster rapper or not.) I'm sure some producers would still sound the same because Dr. Dre hasn't influenced every living producer.
(What truly amazes me, though, is how comfortable some people are with another man [or themselves] disrespecting their sister, mother, grandmother, and/or partner by referring to women as "bitches" and "hoes." I know it's just a word, but it's derogatory and disrespectful.)
