Royce Da 5'9" has been pretty busy as of late. A few weeks a go, the rapper connected with DJ Premier again to release their second collaborative project, PRhyme 2. Shortly after that, the rapper made a massive announcement and revealed the cover art and tracklist to his highly anticipated album, Book Of Ryan. He led the campaign with the single, "Boblo Boat" which featured a very rare guest appearance from J. Cole. While a Cole guest feature is rare to come by these days, Royce explained how the song came about and apparently, Big Sean was the catalyst in the scenario.

Royce Da 5'9" recently spoke to XXL about how his lead single off of Book Of Ryan came about. He said it began when Cole hit Sean up for a studio during his day off in

"He called Big Sean and asked him if he knew of a studio," he said. "So Sean was like, 'Hold on, let me hit Royce'... I'm like, 'Of course he can use my studio."

While Royce was getting ready to leave the studio, Cole inquired about hearing some new music from him which ultimate led to their collaboration on "Boblo Boat."

"He came through and I thought he was just going to use the studio—I was about to leave. He was like, 'Yo, let me hear something. You got some music or something that you're working on?' I played him a few things, he started playing me some beats. One thing led to another and we did a few things." Royce said. 

It looks like we have to thank Big Sean for bringing the two of them together. Royce has previously sung high praises for Cole's work so it was about time that we heard a collab from the two.
