"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.
