Dude, it would take you two seconds to look it up, lol. Mad outlets talked about the payments. Including Kemp himself. That's why KM was on Twitter defending himself about it.
Cube is one of my favorite MC's of all-time. And he's made some mistakes, but I never saw him as a sellout. I feel like Cube tries to get it right. KM is just taking checks and doing the work as black man, that the people who pay him feel they can't do as openly. That's just selling out. He has one message on wax, and lives his life in a whole different way. But not in a way like the fake "street" MC's, but in a way that shows he's just mad fraudulent and for sale.
