UPDATE 3/12/15 2:37 p.m.: Looks like Revolt took down the video.
It's always fascinating to get a window into the studio of a visionary musician, and even more so when that visionary is Kanye West. So this video (via Revolt) of 'Ye and Diddy in the studio working on "All Day," the booming single from Kanye's forthcoming So Help Me God, is revelatory in existence alone. Worth viewing, too, just to see the two cracking wise about the song's ferocious nature, including this gem from Mr. West: "When I see my daughter run through the sprinklers for the first time in her life, I feel like that's not gonna be playing."
