This is by far my favorite Beatles album (and I own all of them).
It has material from their most creative period and effectivly abandons the "#1 hits" format that Beatles CD's have gotten locked into and not acknowledged other good songs like "I Am the Walrus" or "A Day In the Life". It also includes material from the "White Album", which as good as it is, is always ignored on Beatles hits discs.
Furthermore all four members are given recognition not just John and Paul; "Octapus's Garden" by Ringo and such songs as "Here Comes the Sun" and others by George are included, whereas the new compilation "1" only features one George song: "Something", which is a superb song, but not a sufficent tribute to the Dark Horse in itself.
Also included are full lyrics to all of the songs. This is especially appreciated for songs like "Come Together" on which one can easily forget the words. There are also photographs in the 24-page booklet,which is quite a lot, considering most of the Beatles albums are completly devoid of any notes at all.
Overall a five star disc because not only does it include hits, it has B-sides like "Don't Let Me Down" and "Revolution", full lyrics to all songs, and it acknowleges all four members. Easily ten stars!
