The collection covers the most part from the commercially successful and in my opinion best creative period of madonna. My reason for buying were really only: Like a Virgin, True Blue and Like A Prayer and bedtime stories - anything else was interested not so - but was unbeatable in this bundle and to trade price for lightning-deal - therefore clear recommendation
I have deliberately written "for people who like Madonna" - for real fans this compilation can save actually or are those fans who were forced to hold everything (collectors) :-) for casual listeners Madonna but makes perfect sense
