Years on Def Jam: 2006-Present
Signature Def Jam Song: "B.M.F. (Blowing Money Fast)" (2006)

The Boss's studious approach to the music game were highly underrated at first. His work ethic and ear for beats are top tier. He survived the C.O. scandal and a fire fight with 50 by putting out consistent quality with the both legends and new talent on a relentless basis. And he doesn't look like he's going to stop.
