Jay Z served as president of Def Jam Recordings from 2004 to 2008, and during that time helped to launch the careers of artists Rihanna and Ne-Yo, among others. These days, it's just kind of a given how Jay is and always has been an entrepreneur as much as an MC (just look at TIDAL).
But Jay apparently got a little push from none other than Mariah Carey before he assumed the top role at Def Jam back in 2004. As former Def Jam chairman and CEO L.A Reid recently revealed on a Rap Radar podcast (part of the Play.It podcast network), he reached out to Carey and admitted he needed a hand figuring out what to do with the label.
Carey's solution was, of course, "hire Jigga!" And so Reid did -- right after Jay strolled into the Def Jam office shortly after Carey's recommendation.
"I was like wait, they choreographed this," Reid told Rap Radar. "That was too good. He was so on time and it worked out."
