"844. The Game ft Kokane – Hard Liquor (Prod. by Dr. Dre)"
isn't it Jelly Roll?
Edit; it is
"Dubcnn: Speaking of Game, a big fan favorite was the track "Hard Liqour" which people first thought that you produced, while others got the hook mixed up with Kokane...
Jelly Roll: No, I didn't produce that! I only sang on it. They always did that to me! Jelly Roll did not produce "Hard Liquor"! Quote quote quote. I only wrote and sang the hook."
