Music never contributed to the progagation of the species? I beg wholeheartedly to differ! I don't think I have to go into detail here, do I?Let me tell this story...... many moons ago when I was in college taking advanced jazz theory (no I don't remember any of it), the professor made us listen to Thelonious Monk's "Round Midnight." Well, let me tell you, it made my temperature rise and my heart beat fast. And there weren't any words!
No wonder the French tried to ban jazz in the 20s.
I think genetics play a large part in a lot of things, whether we like to admit it or not.
