What is "good" music?

edit: @spidey: Lots of tribes out there still manage to make real GOOD music naturally. They learn good beats on drums and learn to control their pitch and tone while singing. I think that alone says a lot.

I think you're leaning more to the tribal music that we as westerners find enjoyable because of their instruments and such, rather than the tribal music we ignore because it's a bunch of bird calls and clattering of instruments in a wild fashion. I'll look for a video of the kind I'm talking about later.
