Bests & Worsts Reviews from Amazon

How can I choose a CD to buy when I can't see the tunes on the CD listed??? I can't buy any more CDs via Amazon via blind listings. I used to be able to preview the tunes. This led me to MANY purchases. What is going on? I hope you realize that many of your CDs are not listed on Wikipedia simply because they were not original offerings, but are actually superb remixes. Why are you doing this??? Adios
