ABBA是瑞典流行乐团，于1972年由AgnethaFältskog，BjörnUlvaeus，Benny Andersson和Anni-Frid Lyngstad在斯德哥尔摩成立。该组的名称是其名字首字母的首字母缩写。它们成为流行音乐史上最具商业成功的行为之一，从1974年到1982年在全球排行榜上名列榜首.ABBA在英国布莱顿的The Dome赢得1974年欧洲歌唱大赛，为瑞典队赢得了第一场胜利。他们是参加比赛最成功的团体。

据估计，ABBA在全球的总唱片销量约为1.4亿至5亿张，成为有史以来最畅销的音乐艺术家之一。 ABBA是来自非英语国家的第一批在英语国家的图表中取得一致成功的团体，包括英国，爱尔兰，加拿大，澳大利亚，新西兰，南非和美国。他们在英国连续创下八张一号专辑。该乐队在拉丁美洲也取得了巨大成功，并以西班牙语录制了他们的热门歌曲。

在乐队活跃的岁月里，它由两对夫妇组成，一个是AgnethaFältskog和BjörnUlvaeus，另一个是Anni-Frid Lyngstad和Benny Andersson。随着人气的增加，他们的个人生活受到影响，最终导致两次婚姻的崩溃。这种关系的变化反映在乐队的音乐中，后者的乐曲以更深刻和更内省的歌词为特色。

在ABBA于1982年12月解散后，Andersson和Ulvaeus取得了成功，为舞台创作音乐，而Lyngstad和Fältskog追求独立的职业生涯并取得了成功。 ABBA的音乐在1989年购买ABBA的目录和唱片公司Polar by Polygram之前一直没有受到欢迎，这为1992年9月国际重新发行所有原创材料和新的Greatest Hits（ABBA Gold）系列奠定了基础，成为全球畅销书。几部电影，特别是穆里尔的婚礼（1994年）和沙漠女王的普里西拉历险记（1994年），进一步激起了对该团体的兴趣，并催生了几支致敬乐队。 1999年，ABBA的音乐被改编成成功的音乐剧Mamma Mia！在全球巡回演出。 2008年上映的同名电影成为英国当年票房收入最高的电影。续集，妈妈咪呀！ Here We Go Again，于2018年发布。

2005年，ABBA荣获欧洲歌唱大赛50周年庆典，当时他们的热门歌曲“滑铁卢”被选为该赛事历史上最好的歌曲。该乐队于2010年入选摇滚名人堂。2015年，他们的歌曲“Dancing Queen”入选了唱片学院的格莱美名人堂。

在2018年4月27日，宣布该乐队在35年不活动后录制了两首新歌，名为“我仍然对你有信心”和“不要让我失望”。 2018年9月18日，安德森在接受采访时表示他们仍在制作这些歌曲，可能还有第三首歌曲;它们将于2019年发布。

ABBA are a Swedish pop group 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 at The Dome in Brighton, UK, giving Sweden its first triumph in the contest. They are the most successful group to have taken part in the competition.

Estimates of ABBA's total record sales are around 140 million to 500 million records worldwide, making them one of the best-selling music artists of all time. ABBA are 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. They have a joint record 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.

During the band's active years, it was composed of two couples, the one being Agnetha Fältskog and Björn Ulvaeus, the other Anni-Frid Lyngstad and Benny 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.

After ABBA disbanded in December 1982, Andersson and Ulvaeus achieved success writing music for the stage,while Lyngstad and Fältskog pursued solo careers with mixed success. ABBA's music declined in popularity until the purchase of ABBA's catalogue and record company Polar by Polygram in 1989 enabled the groundwork to be laid for an international re-issue of all their original material and a new Greatest Hits (ABBA Gold) collection in September 1992, which became a worldwide bestseller. Several films, notably Muriel's Wedding (1994) and The Adventures of Priscilla, Queen of the Desert (1994), further revived interest in the group and spawned several tribute bands. 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.

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. The group was inducted into the Rock and Roll Hall of Fame in 2010. In 2015, their song "Dancing Queen" was inducted into the Recording Academy's Grammy Hall of Fame.

On April 27, 2018, it was announced that the band had recorded two new songs after 35 years of being inactive, named "I Still Have Faith in You" and "Don’t Shut Me Down". On September 18, 2018, in an interview, Andersson said that they are still working on the songs, with possibly a third one written; they are set to be released in 2019.
