I have a book here- downloadable from the internet- by Philip Dorrell. It's called "What is Music? Solving a Scientific Mystery".
It goes into mathematical matrices and Neural maps, but it has two very simple and plain tests for things like this.
1. The Grandchildren test.
This test goes like this; if music or knowledge of music is fundamentally important to humanity, it must have a beneficial evolutionary effect. Therefore any valid theory of music must be able to explain how music helps someone to have more grandchildren.
How many grandchildren have the inventors got?
2. The Luxury Yacht test.
This one goes like this. If a person claims to understand the mechanism for creating successful music, they must be able to prove this by creating music successfully. Since it is commercial success that is the issue here, they must therefore be commercially successful. So the basic question is, do the inventors have luxury yachts?
The second question is, if the device really did create commercial success, would they be telling us about it or cruising in the Seychelles?

Logically this must be nonsense, as well as for all the other reasons given above in previous posts.

I recommend the book if you are interested in going much deeper into what music is, from the point of view of a mathematician.
