The Complete Studio Recordings is a box set of all of the studio material released by the Swedish pop group ABBA. It was released on 7 November 2005 and consists of 9 CDs and 2 DVDs, plus a full colour booklet with timeline and photos. Another booklet containing the complete lyrics was also included.  　　There is one CD for each original studio album. These CDs also include bonus tracks in the form of non-album tracks and non-English versions. The final CD contains additional rare tracks, primarily material released after the group's final studio album. Of particular interest is the rare alternate mix of "Waterloo", which has never been available on CD before. The extended mono version of "On and On and On"—featuring an extra verse and previously only available as the soundtrack to the song's video—is also released on CD for the first time.
