“Obsession” was originally written and recorded as a duet by songwriter Holly Knight and musician Michael Des Barres in 1983, although the recording did not perform well. This version was prominently featured in the 1983 film A Night in Heaven, most notably in a scene in which Christopher Atkins bumps and grinds in Lesley Ann Warren’s face in sync with the rhythm of the song. The song was featured on the film’s soundtrack, but did not receive enough attention to warrant much radio play or a place on any Billboard charts. That version was also featured in the theatrical trailer to the 1986 film 9 1/2 Weeks, starring Mickey Rourke and Kim Basinger.
The track was covered in 1984 by the Synthpop-New Wave group Animotion. The song hit number six in the United States, and number five in the United Kingdom in early 1985, helped by a distinctive video that received heavy rotation on MTV.
