It's simple, and I've said it a couple of times, Wiz has no "conscious" songs, Outkast has quite a few. So when most people hear Rosa Parks who are familiar with Outkast they feel that was a mistake not to be lambasted, plus rosa parks isn't a metaphor for any negative shit. Wiz on the other hand, well if all you talk about is weed, how much money you got, the killaz you got on board, then make a song fuckin off a leaders name...Well you don't have any leverage. Nas has some goosd shit but he confused.
