The album's critical and commercial success was bolstered by the worldwide success of its single "Tainted Love", a cover version of a soul song by Gloria Jones, which topped charts worldwide and became the best-selling British single of 1981 in the United States—as a result of the single's success the album had reported advance orders of more than 200,000 copies.  The album produced two more top five singles in the UK with "Bedsitter" and "Say Hello, Wave Goodbye".

Mutant Moments: Mutant Moments is a short EP, independently financed and produced by Soft Cell, a synthpop/new wave duo who would later achieve fame with their groundbreaking hit cover of the Gloria Jones song "Tainted Love".  Only 2000 copies were pressed, originally by Soft Cell, on Big Frock Records, then later by a Japanese fan club, making the record extremely rare and prized by collectors and fans alike.  The duo, who attended Leeds Metropolitan University, originally developed a cult following with their performances which routinely included bizarre sexual imagery and visuals representing sexual themes.  Some examples include instances where singer Marc Almond would smear his body with cat food, simulate sexual intercourse with a full-length mirror, or appear onstage in drag.

Page (Swedish band): Page is a Swedish synthpop band.  Page is often credited with being the first band to bring synthpop music to Sweden.

In the 1980s, the band had little success outside of Sweden.  A planned US album was recorded, but then shelved by Columbia Records.  They continued to have numerous hit singles in their home country of Sweden.  They were basically defunct for most of the 1990s, but had a resurgence with the album "Remembering the Future" in 1999.

Elegant Machinery: Elegant Machinery is a Swedish synthpop band.  Borrowing heavily from the likes of Depeche Mode, they are one of few recent bands dedicated to making traditional synthpop music.  Along with such bands as Page, S.P.O.C.K, Sista Mannen På Jorden and Kiethevez they define the sound of the Swedish synthpop movement.
