2 is a compilation album by Swedish pop group ABBA, released on October 29, 1979, to coincide with their tour of North America and Europe, which took place between September and November 1979.

It was ABBA's second chart-topping album of the year (after Voulez-Vous)[citation needed] and featured "Gimme!

"Angeleyes" was included primarily due to its success as a single in the UK, where it was released as a double A-side with "Voulez-Vous".

"I Wonder (Departure)", a track not released as a single (excluding the live version that served as the B-side to "The Name of the Game"), was also featured.

2 achieved massive commercial success in Japan, selling an excess of 920,000 units (it was the best-selling album by a non-domestic artist at the time, until Michael Jackson's Thriller sold over 1 million copies in the 1980s).
