ABBA's fifth album was a marked step forward for the group, having evolved out of Europop music into a world-class rock act over their previous two albums, they now proceeded to absorb and assimilate some of the influences around them, particularly the laid-back California sound of Fleetwood Mac (curiously, like ABBA, then a band with two couples at its center), as well as some of the attributes of progressive rock. That they did this without compromising their essential virtues as a pop ensemble makes this album seem even more extraordinary, though at the time nobody bothered to analyze it ? The Album was simply an incredibly popular release, yielding two British number one singles in "The Name of the Game" and "Take a Chance on Me" (which made the Top Five in America, their second-best showing after "Dancing Queen"), and achieving the quartet's highest-ever showing on the U.S. LP charts, reaching the Top 20 and selling a million copies in six months.
