Obsession is a song by Swedish band Army of Lovers. The lyrics were written by Alexander Bard and Anders Wollbeck, and the song is in part inspired by Laurie Anderson's 1981 song "O Superman"—primarily, the "ah ah" looped backing track. Released in August 1991 by Ton Son Ton as the second single from their second album, Massive Luxury Overdose (1991), "Obsession" reached number one on both the radio and the dance charts in Sweden. It also peaked at number two on the Swedish Singles Chart, number four in Belgium, number seven in Austria and Germany, and number nine in Spain. In 1992, Army of Lovers re-released the single exclusively for the United States and includes remixes only found in this version; it reached number 11 on the Billboard Dance Club Play chart.
