i don't care if you don't like rap but tech n9ne is not really mainstream, his cd absolute power is the best cd to workout too, he pumps you up so hard, its unlike anything you'll ever hear. dmx "don't you ever" is another personal favorite, as well as "i just love" we used to play it on my lacrosse bus before every game. "i just love when a nigga bring his whole crew its just a bigger piece of cake for me to chew a whole thru". but hands down for just one song "we all die one day" obie trice feat 50, lloyd banks, proof and eminem. slim's line in that song will pump up a 73 year old man i don't give a fuck rap or not, "i got too much momentum moving in my direction to lose, your shoes will explode as soon as you go to step in them boom, you know how we do it when we come thru g-unit d 1 2 and obie we all move like assasins ski mask and gloves consider this as a warning disaster comes faster than you can react to it" get those you will wanna kill everyone in the gym
