I was on the fence. Based on so many glowing reviews here and on SH, I bought the HDtrack download. I usually have the music on, the game in background and a book. For this release, I only had the music. I was "uncomfortable". It seemed I had to turn it up much louder than my normal range. The drums were very "in your face". In fact I cannot think of a release I have that is quite this way. I have many jazz albums that I enjoy that were definitely an acquired taste. This one will get several more re-listens. But if I could magically return my download and get my $20 back, I would definitely consider it.
