"Hung Up" is a song by American singer-songwriter Madonna. It was written and produced in collaboration with Stuart Price, and released as the first single from her tenth studio album, Confessions on a Dance Floor. Initially used in a number of television advertisements and serials, the song was released as the album's lead single on October 17, 2005. It has since also made an appearance on her 2009 greatest hits album, Celebration. It also became Madonna's first track to be released to iTunes.

"Hung Up" prominently features a sample of the pop group ABBA's hit single "Gimme! Gimme! Gimme! (A Man After Midnight)", for which Madonna personally sought permission from ABBA songwriters Benny Andersson and Björn Ulvaeus. Musically the song is influenced by 1980s pop, 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.

Frank Vincent Zappa (December 21, 1940 – December 4, 1993) was an American composer, singer-songwriter, electric guitarist, recording engineer, record producer and film director. In a career spanning more than 30 years, Zappa wrote rock, jazz, orchestral and musique concrète works. He also directed feature-length films and music videos, and designed album covers. Zappa produced almost all of the more than 60 albums he released with the band The Mothers of Invention and as a solo artist. While in his teens, he acquired a taste for percussion-based avant-garde composers such as Edgard Varèse and 1950s rhythm and blues music. He began writing classical music in high school, while at the same time playing drums in rhythm and blues bands; he later switched to electric guitar.

He was a self-taught composer and performer, and his diverse musical influences led him to create music that was often impossible to categorize. His 1966 debut album with The Mothers of Invention, Freak Out!, combined songs in conventional rock and roll format with collective improvisations and studio-generated sound collages. His later albums shared this eclectic and experimental approach, irrespective of whether the fundamental format was one of rock, jazz or classical. His lyrics—often humorously—reflected his iconoclastic view of established social and political processes, structures and movements. He was a strident critic of mainstream education and organized religion, and a forthright and passionate advocate for freedom of speech, self-education, political participation and the abolition of censorship.
