ABBA Gold: Greatest Hits is a compilation album by the Swedish pop group ABBA. It was released on 21 September 1992 through PolyGram, making it the first compilation to be released after the company had acquired Polar Music, and thus the rights to the ABBA back catalogue. With sales of 30 million, Gold is the best-selling ABBA album, as well one of the best-selling albums worldwide. Since 1992, it has been re-released several times, most notably in 1999 as the first remastered reissue to mark the group's 25th anniversary of winning the Eurovision Song Contest 1974, in 2008 to coincide with the release of the film Mamma Mia! and most recently in 2014 to mark the group's 40th anniversary of winning the Eurovision Song Contest. Background and Overview Polar had only produced and distributed ABBA's records in Scandinavian countries, licencing the recordings for release by different companies around the world (such as Atlantic in the US and Epic in the UK). This meant there were many different compilations released in different parts of the world. As these licences were renewed every three years, between 1989 (when PolyGram acquired Polar) and 1992 all of these licences had expired. Although PolyGram had made all of the original studio albums available (along with the 1986 live album which had originally been issued by Polydor worldwide), all previously released ABBA compilations had been deleted. Erasure had released a 4 track ABBA cover EP, Abba-esque, in summer 1992 which topped charts around the world showing there was still a strong interest in ABBA's music. Rather than issue the multiple previous compilations, PolyGram put together a new collection, optimised for the CD format. Gold: Greatest Hits was well received by the music-buying public, and went on to be one of the best-selling albums of all time. It has been re-released in various "special" or "remastered" releases: Regional variations and tie-ins Australasian editions The 1992 and 1999 editions released in Australia and New Zealand (and some other territories in that area) had a modified track listing (see below) to include three local hits, replacing three other songs on the international edition.
