Which famous song did ABBA release as a New Year's-themed single in 1980?

ABBA released “Happy New Year” as a New Year’s-themed single in 1980. The Swedish pop group recorded the song for its 1980 album Super Trouper, and it became one of the group’s best-known songs connected with the holiday.

The lyrics look beyond a single celebration and express uncertainty about the future, giving the song a more reflective mood than a straightforward party anthem. Benny Andersson and Björn Ulvaeus wrote the music and lyrics, while Agnetha Fältskog sings much of the lead vocal in the recording.

The song was released in several markets under different commercial circumstances and did not become an immediate worldwide chart leader on the scale of some ABBA singles. It later gained recurring seasonal popularity and is now frequently played around New Year’s celebrations. It is distinct from “Auld Lang Syne,” the traditional song often sung at midnight in English-speaking countries, and from ABBA’s unrelated hits “Dancing Queen” and “Mamma Mia.”
