The Decca Records release sold 130,000 copies in the week ended August 10, becoming the second soundtrack this year to reach the summit, following the "Juno" soundtrack in January.
The film soundtrack to "Mamma Mia!" features actors like Meryl Streep, Amanda Seyfried and Pierce Brosnan belting out ABBA favorites. The film has earned $104 million at the North American box office.
The last year two or more soundtracks earned the top spot on the Billboard 200 was in 1998, when "Titanic," "City of Angels" and "Armageddon" all had their turn at No. 1.
ABBA has never had a top 10 album on the Billboard 200; the Swedish pop act’s highest charting set is 1978’s "The Album," which peaked at No. 14.
