Gold Nigga

Goldnigga is the first studio album by the New Power Generation. It was only made available for sale at some concert venue merchandise stalls on tour in 1993, through Prince's 1-800-NEW-FUNK telephone retail outlet, and at Paisley Park during the 2001 Celebration. It is long out of print, thus very scarce and can fetch high prices second-hand.
The track "Guess Who's Knockin'" referenced Paul McCartney's "Let 'Em In" without credit. Probably to avoid any legal difficulties, the track was removed from second and subsequent pressings, making initial copies of the album even more highly sought after.
