OK, this is kind of a lame post, only a link to this single NY Times article, which is about the stone age flutes that have been excavated and reconstructed from sites in Germany. BUT, the flutes are at least 35,000 years old, and were found near sculpture as well.
Think about that--human beings (and possibly Neanderthals, this was from an approximately 10,000-year period of co-existence), while living in caves and hunting daily for food, not only took the time to carve flutes, but had to figure out how to make a flute in the first place. That's no mean feat, and to me demonstrates that making music, having music in your life, is something very basic and intrinsic to human beings. I also imagine that with a fire or two going, the acoustics and lights in those caves got pretty cool at night.
(Worth noting that the flute in the article was found a few feet away from this buxom sculpture--looks like sex & music have been connected for a long, long time.)
