Today's Song Of The Day goes to Southern rapper T.I. for his Grammy Award-winning track, "What You Know". That's right, T.I. won a Grammy Award for Best Rap Solo Performance with this smash hit, which is often ranked as the top song to come out of 2006. This song is a straight up banger, and that's mostly due to the amazing production by DJ Toomp. This is not T.I.'s most lyrical song, so his long-time producer DJ Toomp stepped in to provide a beat that turned what could have been an average track, into T.I.'s most successful song to date. Must be one hell of a beat right? Check it out for yourself. Enjoy!
