While I agree Nas is more of an "artist" than Jay, and is in my opinion the greatest emcee of all time, it kinda disturbs me to see people view Jay as some kind of superficial artist. Granted to be fair, nobody that I've seen in this thread has come out directly and said that, but there's definately a feeling presented in the opening post and afterwards that he's superficial and lacks substance, which isn't entirely true.
I agree that he definately markets himself far better than the average artist, including Nas, but still he's not as 90210 as detractors would like one to believe. Particulary with the Black album and Blueprint, that nikka poured out his heart quite a bit on those albums.
