ABBA’s Greatest Hits has sold millions of copies around the world. Here you see it honored with a Gold British Phonograph Industry (BPI) award…
During the 1970’s the Swedish group ABBA proved that a rock band could achieve enormous success even though it was based in a relatively small country and had no major concert appearances in the main bastion of rock, the U.S. Yet it achieved record sales in excess of many of the most successful American Bands. – The Encyclopedia or Pop, Rock, and Soul
ABBA’s Greatest Hits of course has a back story, here’s more from Wikipedia…
ABBA (/ˈæbə/, Swedish pronunciation: [ˈabːa]) is a Swedish pop supergroup formed in Stockholm in 1972 by Agnetha Fältskog, Björn Ulvaeus, Benny Andersson, and Anni-Frid Lyngstad. The group’s name is an acronym of the first letters of their first names. They became one of the most commercially successful acts in the history of popular music, topping the charts worldwide from 1974 to 1982. ABBA won the Eurovision Song Contest 1974, giving Sweden its first triumph in the contest. They are the most successful group to have taken part in the competition.
During the band’s main active years, it was composed of two married couples: Fältskog and Ulvaeus, and Lyngstad and Andersson. With the increase of their popularity, their personal lives suffered, which eventually resulted in the collapse of both marriages. The relationship changes were reflected in the group’s music, with latter compositions featuring darker and more introspective lyrics.[2] After ABBA disbanded, Andersson and Ulvaeus achieved success writing music for the stage,[3][4] while Lyngstad and Fältskog pursued solo careers.[5][6] Ten years after their disbanding, a compilation, ABBA Gold was released, which became a worldwide bestseller.
In 1999, ABBA’s music was adapted into the successful musical Mamma Mia! that toured worldwide. A film of the same name, released in 2008, became the highest-grossing film in the United Kingdom that year. A sequel, Mamma Mia! Here We Go Again, was released in 2018. That same year it was announced that the band had recorded two new songs after 35 years of being inactive.[7][8]
Estimates of ABBA’s total record sales are over 380 million,[9][10] making them one of the best-selling music artists of all time.[11] ABBA were the first group from a non-English-speaking country to achieve consistent success in the charts of English-speaking countries, including the United Kingdom, Ireland, Canada, Australia, New Zealand, South Africa and the United States.[12] They had eight consecutive number-one albums in the UK. The group also enjoyed significant success in Latin America, and recorded a collection of their hit songs in Spanish. ABBA were honoured at the 50th anniversary celebration of the Eurovision Song Contest in 2005, when their hit “Waterloo” was chosen as the best song in the competition’s history.[13] The group was inducted into the Rock and Roll Hall of Fame in 2010.[14] In 2015, their song “Dancing Queen” was inducted into the Recording Academy‘s Grammy Hall of Fame.[15]
