Youngmoe Royce is way tight... ive been listening to him for a LONG ass time... but you ever heard Proof battle? He can freestyle like a motherfucker. If you download the 18 minute Tim Westwood Freestyle, he even outshines Eminem... by far.
It would be a good battle.
Any other D12, Royce would win. But D12 is still coo imo
