Jay-z signed a distribution deal with Universal, which owns Roc-a-fella.
A lot of former Jay-z/Roc-a-fella employees and his friends work at Def Jam, which Roc-a-fella is under. So it seems like nothing more than some swagged out shyt to do.
I think the plan is the merge Roc-a-fella and Roc-Nation, since Roc-a-fella still own some of Jay's masters until this and next year, the remaining masters are then returned it's returned to Jay.
So I think it's probably just some swagged out shyt or it has to do with his masters. Or both.
