He's gone wild with Steve-O, shared paint with the Cavs, and sparked up with Juicy J and (likely) Wiz Khalifa. He was signed by Diddy. He covered XXL magazine. And his track, "Invincible," has been used as theme song by both the NFL and the WWE.

Crossfade: What was the bigger thrill, having "Cleveland" become the official track of the Cavaliers or having "Invincible" blast off WrestleMania XXVIII?

What kinda reaction does "Cleveland" spark in the Cavs' house?
Pride and sweat.
