Jay-Z has announced he will release a surprise new album next month.
Titled Magna Carta Holy Grail, it will be available for free download to the first million Samsung Galaxy SIII, Galaxy S4 and Galaxy Note II users on July 4, with the Magna Carta app unlocking the album.
In the advert, Jay-Z said: "The album is about, like this duality of how do you navigate through this whole thing, through success, through failures, through all this and remain yourself.
"We don't have any rules. Everyone's trying to figure it out. We need to write the new rules.
"The idea is to really finish the album and drop it. Giving it to the world at one time and letting them share it, and it goes out."
