Madonna realsed "The Immaculate Collection" in november 1990. Contaning nearly a decades work of greatest hits. Staying at No.1 for 9 weeks and selling over 22,000,000 copies it was a worldwide thornominuion. In early 1991 Madonna realsed "The Hoilday Collection" which contained 4 tracks it was the 2nd CD single of the 3rd time re-issuded hoilday. It contained Hoilday, True Blue, Who's That Girl & Causin' a commotion. The last 3 tracks where the ones left off the Immaculate Collection so if you have both of them you own the "Ultimate Collection". Hoilday is a slighty different version Madonna re-recorded it as he last too realses of it made her sound like Miny Mouse on Heluim. True Blue ect. are the orginal edits produced by Madonna, Pat Leonard & Steve Bray. This Edition is party/pop/rock and is really up too beat! In terms an album but also a single it is a bargin! that will give you a life time of listning enjoyment!
