I know exactly what your saying, although it`s horrible to put down musical beauty to maths. That`s like looking at the person you love most in the world as nothing but a predetermined collection of molecules.
Polyrythmic structures especially in melody are extremely hypnotic.
In fact to induce a hypnotic state one of the most reliable methods is with alpha level sounds played over each other so they phase in and out polyrythmically. I have a hole recording of alpha state hypnotic audio somewhere, from an oldpsychology lecture.
But again, it`s only one facet of music.
Xanakis is very interesting for looking into the visual reference patterns behind music, fractals etc.
I think there`s a time and a place for a DJ to lead, and play grooves, and a time to play music that actually does something. too much of one thing will always lead to stagnation.
