Confessions on a Dance Floor in the context of "Hung Up"

"Hung Up" is a song by American singer Madonna from her tenth studio album Confessions on a Dance Floor (2005). Initially used in a number of television advertisements and serials, the song was released as the album's lead single on October 17, 2005. Written and produced by Madonna in collaboration with Stuart Price, "Hung Up" prominently features a sample from an instrumental section of ABBA's "Gimme! Gimme! Gimme! (A Man After Midnight)", for which Madonna personally sought permission from its songwriters, Benny Andersson and Björn Ulvaeus. This is one of the few times Andersson and Ulvaeus have given permission to sample one of their songs, following "Rumble in the Jungle" by the Fugees and "Fly with Me" by 98 Degrees.

Musically, the song is influenced by pop music from the 1980s, with a chugging groove and chorus and a background element of a ticking clock that suggests the fear of wasting time. Lyrically, the song is written as a traditional dance number about a strong, independent woman who has relationship troubles. "Hung Up" received critical praise from reviewers, who considered it among Madonna's best dance tracks and believed that the track would restore her popularity, which had diminished following the release of her 2003 album American Life. "Hung Up" became a global commercial success, peaking atop the charts of 41 countries and earning a place in the Guinness Book of World Records. It was Madonna's 36th top ten single on the Billboard Hot 100, tying her with Elvis Presley as the artist with most top ten entries. It also became the most successful dance song of the decade in the United States. "Hung Up" has sold over five million copies worldwide.
