The album celebrates the band's 25th Anniversary singles career starting in 1972 and contains all of ELO's 29 UK hit singles plus other single edits that either didn't chart or were hits in other countries. All the songs included are the edited 7" single versions. It is also the first ELO compilation to feature the song "Across the Border" which was scheduled to be released as an EP track in 1980 but was withdrawn. Although not in chronological order, it is however the most comprehensive assemblage of the band's hits of the many compilations available.
The album reached 60 in the UK Album Charts. The album was also released in Europe with an identical track order under the titles, The Swedish Collection and The Danish Collection.
