ABBA

During the band's active years, the band was composed of two 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 later compositions featuring more introspective and dark lyrics.
