Best CD, hands down, for Madonna fans. She has 36 songs on these 2 disks. ALL her popular and most played songs are on here for your listening pleasure. I have always been a fan of Madonna and this album does not disappoint. I was a teenager in the 80s. I wanted to BE her. As she has grown up and has changed with the times, so have her songs. Ray Of Light and 4 Minutes (with Justin Timberlake) are great examples of how she adapts to make her songs new and fresh. I was fortunate enough to be a part of her stage crew for the 2012 Superbowl here in Indianapolis and watched many rehearsals of the show. The songs Music, Vogue and Like A Prayer that she performed are on the Disc 1.
