Question: What duo is principally known for their 1981 hit version of "Tainted Love" that was influencing to  a Swedish synthpop band founded in January 2002 by vocalist Christer Lundberg and producer Paul Lachenardière?
Context: DaYeene was a Swedish soul/house music group, active in early 1990s.  The group consisted of the sisters Jeanette and Diane Söderholm.  Diane had previously been vocalist in the Swedish synthpop band, Freestyle. Non-Stop Erotic Cabaret is the debut album by English synthpop duo Soft Cell, released in the United Kingdom on 27 November 1981 by Some Bizzare Records.  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". "SOS" is a song by Barbadian singer Rihanna from her second studio album "A Girl like Me" (2006).  It was written by Jonathan "J.R." Rotem, E. Kidd Bogart and Ed Cobb, with production was handled by Rotem, Carl Sturken and Evan Rogers.  It was released on February 14, 2006, as the lead single from the album.  "SOS" is a dance-pop song which samples Soft Cell's 1981 recording of "Tainted Love", a song written by Cobb in 1965.  Critical reception of "SOS" was generally positive, with the majority of music critics praising the inclusion of the "Tainted Love" sample.  Some critics compared "SOS" to Rihanna's debut single, "Pon de Replay" ("Music of the Sun", 2005). Universal Poplab is a Swedish synthpop band founded in January 2002 by vocalist Christer Lundberg and producer Paul Lachenardière.  The band's two members have very different backgrounds: Christer is an old-school synthpop fan, influenced by acts like Soft Cell and Yazoo, Paul is a classically trained musician with roots in jazz, electronica, trance and techno. Soft Cell are an English synthpop duo who came to prominence in the early 1980s, consisting of vocalist Marc Almond and instrumentalist David Ball.  The duo are principally known for their 1981 hit version of "Tainted Love" (#8 US) and 1981 debut album titled "Non-Stop Erotic Cabaret". Gloria Richetta Jones (October 19, 1945, Cincinnati, Ohio) is an American singer-songwriter from Los Angeles, California.  She recorded the 1964 song "Tainted Love", later a hit for the British synthpop duo, Soft Cell.  She was the girlfriend of glam rock artist Marc Bolan of the band T. Rex until his death in 1977. 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 is a Swedish synthpop band.  Page is often credited with being the first band to bring synthpop music to Sweden.  Their music and band members (particularly Eddie Bengtsson) influenced many subsequent Swedish synthpop acts, including Elegant Machinery, S.P.O.C.K, Sista Mannen På Jorden and KieTheVez. NASA is a Swedish synthpop band fronted by Patrik Henzel and Martin Thors.  They debuted in 1983 with a song for a Swedish film.  In 1985 they had a Swedish top ten hit "Paula".  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 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.
