“U and Dat”, sometimes spelled as “U N Dat” was the 2nd single off E40’s My Ghetto Report Card. It can be considered a “summer jam” due to its release in late June, early July. The song received respectable play, on both TV and Radio, but it wasn’t as memorable nor popular as “Tell Me When To Go.” However, it did manage to peak at #13 on the Billboard Hot 100, making it the highest-charting single in which 40 was the lead artist.

The single did help to popularize T-Pain as a hook/chorus singer.

The video features cameos from Katt Williams and Lil Jon (who produced the song), and features many females in a black room, presumably to be a club as well as many scenes involving a Dodge Charger and a Porsche Cayenne.
