To celebrate
ABBA's 40th anniversary, Polydor released the 2012 compilation
The Essential Collection, which includes 39 songs by the Swedish hitmakers and a 12-page booklet. The two-CD album is basically an update of the 2002 compilation The Definitive Collection, adding several Japanese A-sides to that collection's track list ("Bang-a-Boomerang," "That's Me," "One Man, One Woman," and "Happy New Year").
The Essential Collection is also available as a DVD with 36 music videos and promo clips (including two previously unreleased Spanish videos) and as a limited deluxe edition with both CDs and the DVD in a hardcover book containing a 24-page booklet with liner notes by
ABBA biographer Carl Magnus Palm. ~ Christian Genzel
