I bought this CD because I finally wanted to have a collection of Kylie's greatest hits. On the first CD are their old songs, which are still awesome and you can also listen quietly now. The second CD includes their newer songs that are more naturally up to date. If the songs you listen to compared, it is found invariably that Kylie has made an amazing development over time. Both the old and the new song can be heard. Not just for Kylie fans.
