Years ago, I tried this product and like it so much, I used to sell and ship physical copies of it to some of my customers of Hebrew, Spanish, and other foreign language products. I have since got out of the business of shipping products, but still enjoy this music, which is not available digitally.
The technology is amazing, and you might want to try it to see if you can truly improve your brain. They have different programs now, where you can listen to classical music encoded with their technology, or they even have a tool, where you can take your own music and encode it. The amazing thing is, that it doesn’t require headphones, as do many other brain entrainment systems.
