Robin Scott describes the genesis of "Pop Muzik" this way:
I was looking to make a fusion of various styles which somehow would summarise the last 25 years of pop music. It was a deliberate point I was trying to make. Whereas rock and roll had created a generation gap, disco was bringing people together on an enormous scale. That's why I really wanted to make a simple, bland statement, which was, 'All we're talking about basically (is) pop music.'
The single was released in the UK first, peaking at number two on 12 May 1979, unable to break Art Garfunkel's 6-week stint at number one with "Bright Eyes". In August of that same year, it was released in North America, where it eventually climbed all the way to number one in Canada on 27 October and in the US on 3 November.
Along with Scott, other musicians who played on the track were his brother Julian Scott (on bass), then unknown keyboardist Wally Badarou, Canadian synthesiser programmer John Lewis (who died of AIDS in 1985), Drummer Phil Gould (who later became one of the founding members of the group Level 42), Gary Barnacle and Brigit Novik, the backing vocalist, credited as "Brigit Vinchon" on the records and sleeves.
The single was bolstered by a promotional video that was well received. The clip featured Scott as a DJ singing into a microphone from behind an exaggerated turntable setup, at times flanked by two female models who sang and danced in a robotic manner. One of the sight gags in the video depicted Brigit Novik dressed in blue who actually recorded the backup vocals which are then mimed by the models.
The single's B-side, "M Factor", was featured in two different versions. The original cut appeared on the first UK and European releases of the single, while a slightly remixed version appeared on the single released in the United States and Canada.
The image of the baby on "Pop Muzik"'s single disc pictures Robin Scott's daughter, named Berenice, who is now a singer and piano/keyboard player and composer and involved with her father's friend Phil Gould and Wally Badarou projects.
The UK 12-inch single version was notable for the A-side having a double groove such that the two tracks ("Pop Muzik" and "M Factor") both started at the outer edge of the record and finished in the middle (with a long silence at the end of "M Factor" since the track was the shorter of the two). This resulted in a random selection of the two tracks, depending on which groove the needle landed in the lead-in. To further market this idea, the UK record sleeve stated "B side included on A side, full length disco mix of Pop Musik on Seaside". 'Seaside' (in other words "C side") was a simple play on words as the letter C, apart from being the logical next "side" after the A and B sides, is pronounced the same way as the English word "sea", and "seaside" means "beside the sea".
The song was remixed and re-released in 1989 where it reached number 20 in the UK Singles Charts.
