Nelson already figured out his ideal song.
Vitor - LL, Mama said knock you out. Just due to the comeback reference in the song.
War Machine - SOD, Kill Yourself. Just tired of stupid people and when we have stupid MMA people, it's only worse.
Hardy - Prodigy, Firestarter. Just seems to fit IMO. He talks good crap and seems to be backing it up.
Rampage - 3 little pigs by Green Jelly
