Basically, you get 5 studio albums for the price of 1...
It contains all the albums Kylie released since the beginning of the new millennium. I bought this as a gift for a friend who just discovered Kylie Minogue and she simply loves this set. The package is simple and nicely done. Each CD comes in their own cardboard sleeve with their respective album art on the front and the track listing on the back. It comes with a leaflet containing the credits of each CD as well as some pictures that were taken from each albums' photoshoot.
Although some extras would have been welcomed like a separate DVD containing her music videos, "making of" of these albums or even a small documentary on the evolution of Kylie's career during those years... The leaflet could have also contained lyrics off all these songs or maybe handwritten lyrics... but I can't really complain because I was able to get this at a very good price.
Anybody who wishes to have a taste of Kylie's music and does not want to buy the 5 albums (i.e.: Lights Years, Fever, Body Language, X, and Aphrodite) separately should consider getting this (Be warned as it contains no extras). It's no compilation album nor a greatest hit, it's really 5 full blown studio albums in one box.
