The box set mixes the usual hit singles with lesser known album tracks and non-album B-sides, and is most notable for including most of the Secret Messages (1983) tracks that were not released when the intended album was reduced from a double to a single LP as well as B-sides from Balance of Power (1986) singles.
The discs of the box set were labelled with letters "E", "L" and "O", each covering a different compilation set of albums:
- Disc "E" – The Electric Light Orchestra (1971; tracks 1–2), ELO 2 (1973; tracks 3–6), On the Third Day (1973; tracks 7–9) and Eldorado (1974; tracks 10–11) (with the exception of "One Summer Dream" from Face the Music (1975))
- Disc "L" – Face the Music (tracks 1, 3, 5–6), A New World Record (1976; tracks 2, 4, 7–10), Out of the Blue (1977; tracks 11–15) and Discovery (1979; tracks 16–17)
- Disc "O" – Time (1981; tracks 1–2, 6 & 9), Secret Messages (1983; tracks 10 & 18) and Balance of Power (1986; tracks 13 & 16) (with the exception of "Shine a Little Love" from Discovery)
The songs from soundtrack album Xanadu (1980) were not included.
The song "Destination Unknown", which was previously released as a B-side to "Calling America" single, was issued as promo only CD single. This statement is untrue. It was a 10 track sampler, not a CD single.
All tracks written by Jeff Lynne, except "Roll Over Beethoven" by Chuck Berry and Ludwig van Beethoven.
