Your brain has a music room, and evolution would not have gone to the trouble of designing that if it didn't have some benefits. So, that suggests to me that we and our ancestors have had music as a central part of our experience for eons. And we're just beginning to understand how that might be. I think that's fascinating.
There is an enormous inertia that prevents people from change. You must always remember that it is impossible to make something better if you don't make it different - the converse is not true, of course. You cannot make something better unless it is different. And different scares the life out of so many people.
