Sony is running out of stuff to release from NaS. Both Sony and Def Jam are sleeping on the Lost Tapes. Each could release a volume and that would be dope. Other than unreleased music, they could do a compilation of movie soundtrack tracks, etc (Gangster Tears, Escobar 97, Wanna Be Me). If they don't put out the music, they could release more of his videos. His video anthology only goes up through God's Son. Other than that, there is probably not much more.
