Lil Jon-Get Low. That is a fucking badass song, with a great beat and a good club feel. Good song to get a lap dance to
A lot of bass too, if you like that. David Banner's CD sucks, just download Get Down (Like a Pimp) with him and Lil Flip. Anything by Flip is good, he is the best rapper IMHO. My favorite rap song is Da Summa (Remix) by Three 6 Mafia.
