I heard Boldy talk about it before. It never came out because he said Nas didn't like his verse on it. Body also said he wasn't that crazy about his own verse too if I remember correctly.I think that Nas, Mac Miller and Boldy joint that we saw pictures of them in the studio was supposed to be out too.
That compliation I think had a whole tracklist too but never came out, wonder what the deal was. Maybe cause Nas was still signed to Def Jam and the Mass appeal distribution in 2013/14 was with Sony if I remember correctly (It went back forth between Def jam and Sony)
