Tribal people have amazing music, I doubt their drive was money (which didn't exist), fame (didn't exist), or sex (maybe?). Dancing is probably more important for courtship, nearly everyone sucks at that and we're still here.
How many people are interested in folk music? Very few. And in earlier tribal music much less. Any development will stay local, and nobody will be able to stand on the shoulders of giants.
