I can't say that Jay-Z is sstill a credible mc. He's sold out and the only reason why he sells records is because of his fame. DOA is possibly one of his worst tracks of all time. I think that the fate of commercialized hip hop resides on artists like wale, cudi, wiz kahlifa,curren$y and thophilus london. Its up to those guys to change the face of the game while being true to themselves. Because these days most artists aren't from the ghetto or are gang bangers and its up to the new artists to show that face of hip hop.
