Ludacris - Tell It Like It Is
Honestly, I'm impressed with Luda lately. I think he found his rhythm by making records that actually address issues instead of just striving to entertain. You know when you're interviewing an artist and you ask "what word of advice do you have for people coming up in the game?" this song tackles that question head-on. He gets at Chingy, declares support for Hov, and doles out more subliminals to T.I.

Bonus:
Christina Aguilera ft. Ludacris - Ain't No Other Man (Remix)
