"U and Dat" is the second single from E-40's album My Ghetto Report Card. The song features T-Pain and Kandi Burruss, and it was produced by Lil Jon. A remix was released in early August with Juelz Santana, Snoop Dogg, and Lil' Flip. It was featured on an Amp'd mobile commercial. Although it is considered a West coast hip hop song, the song's beat structure incorporates typical southern hip hop snares as well as Lil Jon's signature crunk synths and whistles. The catchy, up-tempo and club oriented southern hip hop track allowed the song to peak at #13 of the U.S. Billboard Hot 100. The track is credited to have popularized the use of T-Pain as a hook singer on hip hop tracks. The song was certified platinum by the RIAA on March 31st, 2016.
The music video is in a club scene and in a car. Most of the video includes T-Pain and E-40 scouting various women, Kandi Burruss and Ashalee Albar being just to name a few. Kandi's part in the video is to push off men around her.
