That is a very perceptive viewpoint. I have always viewed music as more of an emotional vehicle, so I never did see it this way before. A good example is Pink Floyd. Not one love song in their catalog, yet I never viewed their music as technical in a scientific vein.
I do know that they are my go-to source when I need to be calm.
The good thing here then is that music can be used in whatever way the person needs it to be. You can just see it as a free-flowing sensation during stressed times but it can also be applied in a practical sense like for improving focus, and memory.
