The single, first released in the UK in early 1979, was bolstered by a music video (directed by Brian Grant) that was well received by critics. 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. The video also featured Brigit Novik, Scott's partner at the time, who provided the backup vocals for the track.

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 song reached number one in more than seven countries and was one of the most popular singles of 1979.

The song was initially recorded in R&B and funk styles before a friend of Scott suggested using synthesisers. He 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.
