This is one of the best greatest hits packages out there, and it is certainly better than her later compilation "GHV2". This album contains one hit after another, so the song list is exceptional. If I had to say anything negative about this collection (and I know I don't have to, but I do have one small objection), I would say that it is too bad that "Who's That Girl" was left off, as that is one of my favourite songs of hers (not to mention the fact that it was a #1 single). "Oh Father" is also sadly absent, but I know it is the song that ended her incredible string of consecutive top 10 hits. The fact that this song was not more successful is incomprehensible, as it is one of her best songs.
In any event, this is an excellent compilation of Madonna's earlier hits and contains a version of "Express Yourself" that is better than the original album version. Heck, this is an awesome compilation of 1980's hits.
