While promoting "Mamma Mia! Here We Go Again", Cher confirmed she was working on an album that would feature cover versions of songs from ABBA. The album, "Dancing Queen", was released on September 28, 2018. Brittany Spanos from "Rolling Stone" commented that "the 72-year-old makes ABBA songs not only sound like they should've been written for her in the first place but like they firmly belong in 2018". Marc Snetiker from "Entertainment Weekly" called it Cher's "most significant release since 1998's "Believe"" and noted that "the album ender, 'One of Us', is frankly one of Cher's best recordings in years." "Dancing Queen" debuted at number three on the "Billboard" 200, tying with 2013's "Closer to the Truth" for Cher's highest-charting solo album in the US. With first-week sales of 153,000 units, it earned the year's biggest sales week for a pop album by a female artist, as well as Cher's largest sales week since 1991. "Dancing Queen" also topped "Billboard"s Top Album Sales chart, making it Cher's first number-one album on that chart.
