Query: The worst CD ever created...

As a lifelong musician, I have never been so disappointed in a recording as I am with this CD. For a choir as talented and prestigious as the Vienna Boys Choir, I am embarrassed that they would choose such an undertaking. I'm not one to dislike pop music, but this is horrible. I thought the worst music ever created was Madonna's "American Pie," but this takes the cake.
