This is a four record set of 36 songs that came out in 2009. Released on a two disc CD there were a limited number of vinyl versions made and I bought this as soon as I saw it. I was able to listen to three of the eight sides which had had some of my favorites like “Material Girl”,”Lucky Star”,La Isla Bonita”,”Who’s That Girl”,”Frozen”,”Ray Of Light”,”Crazy For You”,”Open Your Heart”,and “Like A Prayer”. Many of these songs were number one hits with videos in heavy rotation on MTV. The songs are full of hooks with good instrumentation and all very danceable. Looking at the liner notes she has a writing credit on all but six of the songs and is co-producer on most of them so I must give her credit for that but I think she is a bit of a nut job now. Now several of these songs are stuck in my head.
