As long as human beings exist on this planet, we will always make music, have traditions, hand down songs and tunes to the next generation, etc etc.
Music will die out when human beings die out....(and the way we are going, that might be sooner than we think!) Until then, enjoy the music that you play/sing.
Reality check here.
Dinosaurs...2 million plus years. Look what happened to them. Had obviously never heard a Child ballad!
