"Deeper and Deeper" is a song by American singer Madonna from her fifth studio album, Erotica (1992). It was written by Madonna, Shep Pettibone, and Anthony Shimkin and was produced by Madonna and Pettibone. In Australia and most European countries, the song was released as the album's second single on November 17, 1992; in the United States, a release was issued on December 8. It was included on Madonna's second greatest hits compilation, GHV2 (2001). A dance-pop and deep house song, it has disco and Philadelphia soul influences; the bridge features instrumentation from flamenco guitars and castanets and features background vocals from the singer's collaborators Donna De Lory and Niki Haris. Lyrically, the song talks about sexual desire, though it has been argued that it is actually about a young man coming to terms with his homosexuality. It includes a reference to Madonna's single "Vogue" (1990).
