To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I heard O Magnum Mysterium on the radio and ordered this right away, based in part on positive and negative Amazon reviews. One said something to the effect that "he's still living in the 19th century." It was intended as a criticism, but that's a good thing to me. The music is still wonderful, but the CD would not play properly. I exchanged it for a second copy and that one had the same problem. I ended up ordering a couple of different recordings of the same music, and am quite happy with those.
