Pretty cool man, although I have no clue how I'd rap over it, plus I have 5,000 commitments to take care of before I could even agree to something like this. If I were to rap over it though, it would have to be under my alias, D. Snuts (featured in my recent song up here, called J.U.M.P.).
I'd highly recommend you check out the NG Hip Hop Club, which can be found in the "Clubs and Crews" section of the audio forums. Good Luck, peace!
