Although this album is a good buy to get the extended versions of some of Summer's greatest dance hits, it is by no means complete. The omission of hits like Bad Girls, Love's Unkind and Love To Love You Baby and of great album tracks like Queen For A Day, Working The Midnight Shift, Lucky and Journey To The Centre Of Your Heart detracts somewhat from the pomise of the album title. On the other hand, the inclusion of the magnificent MacArthur Park Suite makes up for a lot of what is missing. And this extended version of I Feel Love is worth the price of the album. Like another reviewer said, this ought to have been a 2-CD set. It is valuable to replace those old 12" vinyl singles, but not a comprehensive reflection of the Queen of Disco's contribution to dance music.
