Kanye West and Jay-Z's collab album, Watch The Throne, was full of bombastic beats and high-end production, but Kanye West wasn't satisfied. According to Hov, 'Ye wanted a couple of beats Jay saved for his latest album, Magna Carta...Holy Grail, specifically, "Oceans" and "Holy Grail."
From his BBC interview:
"[There were] no lyrics on "Holy Grail" and I recorded "Oceans" and I played those records for Kanye. And he was like, 'No those have to go on Watch the Throne,' so we spent four days arguing about those records and I was explaining to him why it wasn't right for this project and I had a whole idea for making this album called Magna Carta... Holy Grail [part of] the name came after. Four days literally arguing... not like fighting. Well, there was some pushing at one point but not between us, just everyone else got a little excited."
A little excited. In the wake of Yeezus, one can only imagine.
