It is the opening track on the group's third album, the self-titled ABBA. The song was released in September 1975 as its seventh and final single. The song's name is derived from Italian, where it is an interjection used in situations of surprise, anguish, or excitement.

"Dancing Queen" also reached the top five in many other countries.
The Official Albums Chart is a list of albums ranked by physical and digital sales and audio streaming in the United Kingdom. It was published for the first time on 22 July 1956 and is compiled every week by the Official Charts Company (OCC) on Fridays. It is broadcast on BBC Radio 1 and found on the OCC website as a Top 100 or on UKChartsPlus as a Top 200. However, even though number 100 was classed as a hit album in the 1980s until January 1989, since the compilations were removed this definition was changed to Top 75 with follow-up books such as The Virgin Book of British Hit Albums book only including this data. As of 2021, the OCC still only tracks how many UK Top 75s album hits and how many weeks in Top 75 albums chart each artist has achieved.
