What I don't know won't hurt me, so I don't dig to find out who writes their shit or not...but if I know you don't write your shit, you get no respect from me as an mc. I may like the music and listen to it, but no respect is given as far as being an mc. Hiphop isn't pop or rnb where vocals are the "skill", writing is just as much part of the "skill" as flowing/delivery in rap music. Dre isn't an mc, he's a producer who double dips by posing as a rapper instead of just releasing a beat compilation with real mc's rapping over them...same with Diddy, except he's not even a producer. It's not even like they take the lyrics and make them theirs, you can blatantly hear who wrote the rhymes for the most part. Jay's flow is all over Still DRE, and I laughed when i heard the song Pharoah Monch wrote on that Diddy album. I kinda feel insulted by shit like that, like who the fuck wants to hear Diddy try to spit lke Monch.
