I definitly agree with you but this is a natural evolution

The beginning , the 50' : original but rough music
The golden years ,the 60' : original and sophisticated music
The decadence from the 70': sophisticated but plastic music
Afterwards : noise ( well I am an old guy )

Let's go to jazz, now

Dixiland : exciting but childish music
Charlie Parker and the others : the top
Free jazz : no comment

Same consideration for classic music
