Just Blaze said dude was literally homeless, then got big. So I can understand his general mindset of wanting to see the world, buying new clothes/phones/etc. The problem I have is that he could be one of the biggest "underground" rapper in the world, but sits on his ass instead. He could make so much money touring, he hasn't released a single mixtape or album.
I really don't think he'll stay on Roc Nation. Thus far he has wasted two huge opportunities: the aftermath of the official Exhibit C release, and the aftermath of the Roc Nation signing with the Mountain Dew ad.
