Well, it comes down to him also not being an artist. He has, somewhat, done a good job forming into one. There are a lot from that era that were gimmicky and/or propped up in false light. I know all people in Hollywood essentially aim to be famous but those same entertainers from that era who thrive on not being only being in the limelight but it's self-detrimental to them that they remain super relevant.
That being said, I love Nas and he has a good ear. He's beautiful and lovable but I hope he's forming a great support system. I watched some recent clips of him and there appears to be some heavy drug-use and that's sad to see.
