Yung Joc revealed during an interview with Vlad TV, he was booked in the studio with Pharrell in Miami. Skateboard P played the “Blue Magic” beat and gave him a “Rakim flow”, but Yung Joc wasn't feeling it. “I was like, I don't know if that's me,' Yung Joc tells Vlad TV. Later Diddy and Jay-Z walk into the studio and when Pharrell played the beat Jay-Z was instantly feeling it and told Yung Joc if he didn't take it he would.
Yung Joc sure enough gave the Blue Magic beat to Jay-Z and after came “Blue Magic.” with Pharrell on the hook. Jay-Z even mentioned Rakim in the song.
