Hamilton has laid down a vocal for Dr. Dre's upcoming "Detox" that he's "just waiting to see if it's gonna stay or not. I'm keeping my fingers crossed on that one."
But, Hamilton says, he has no insight about when that decision will be made or when we'll actually hear "The Detox."
"Dre's just very, very, very good at getting what he wants. He's pretty talented," Hamilton notes. "When he's producing something he'll try different ingredients, and he'll make what he feels is the best for the project. He just looks at the overall body of work, not just songs or individual collaborations, which I think is smart."
