The One U Wanna C was a promotional single to be released from Prince's 32nd album Planet Earth. It was available only in Holland (following the release of the only commercial single from the album, Guitar). The CD contained only the album version of the song.
Unusually, the video for the song was available almost a year later; made up of photographs from the 21 Nights book, the video acted as promotion for that release.
The single failed to chart, but was nevertheless listed in the Netherlands Tipparade at position 14 in September 2007.
