"Darling Nikki" is a song produced, arranged, composed and performed by American musician Prince and originally released on his Grammy Award-winning 1984 album, Purple Rain. Though the song was not released as a single, it gained wide notoriety for its sexual lyrics and in particular a reference to masturbation. Partly because of the lyrical content of "Darling Nikki", Tipper Gore founded the Parents Music Resource Center, which eventually led to the use of "Parental Advisory" stickers and imprints on album covers. Compared with the slick production of the other songs on the album, "Darling Nikki" was deliberately engineered to have a raw, live feel.
