I'm am happy AF that Jay Z is nowhere near this project. The Lost Tapes is Nas' movement and its another feather in his cap, second in his career only to Illmatic. I'm sure Nas would prefer that it be all about him. The first Lost Tapes was all about Nas with no features I think and hope and all of them should be. Deep down inside, I'm sure there is a least a part of Nas that ain't happy that Jay dropped the day after NASIR. So, in the immortal words of Ether, "fukk Jay Z"! LOL
On the real though, if they work together, put it on a Jay Z album next time.
