It's been done before. I said Eminem's Run Rabbit Run from the 8 Mile soundtrack just because that song pumps me up. Maybe Go To Sleep Bitch the Eminem song with DMX and Obie Trice. Another good one to pump you up. Or Eminem's Nail in the Coffin diss at Benzino. That beat could get anyone's adrenaline going. Eminem and 50 Cent and Tony Yayo's Bump Heads diss at Ja Rule and Murder Inc. Same thing with that beat.
What's funny is - I don't even like Eminem all that much lol.
