Jay made the profit when he sold his albums to Samsung, in turn Samsung thought "Hey if we have this exclusive App for our phone from this big musical talent, say we'll release the album early people will want to buy this Samsung phone in order to get this album. Because hey it's Jay Z and the album is good...right?" Well I don't know if that's the case because I have yet to hear anything about how many new phones Samsung were sold. But I did see that even with Samsung buying those albums Jay still went platinum because of the pre orders. So at the end of the day it was great marketing on his part.
