Starting tomorrow and then throughout the week, BBC Radio 1's Zane Lowe will air his new interview with Jay-Z. According to NME, Jay revealed to Lowe that he had already started working on the Magna Carta Holy Grail tracks "Holy Grail" (featuring Justin Timberlake) and "Oceans" (featuring Frank Ocean) around the time he was working on Watch the Throne with Kanye West.

Jay said he and Kanye agreed that after they did the album together, they'd start working on their new solo albums. Jay made those two tracks and played them for Kanye, which instigated a four-day argument about if they should've been on WTT or held for MCHG:

"[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."

Jay also explained that the arguing was civil. "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."
