"Number One" is the first track we've heard from R. "That Piss Could Be Digital" Kelly since the raunchy "#1 Fan" back in April, and this isn't far off: It's about how the sex he's having with his girl is number one. Keri Hilson does a verse with Kells on the track, and she and him do some cross-country singing in different radio stations in the song's big-budget video. It remains to be seen if Kelly can rehab his image, but this song might start that process.
