Douglas Adams once developed a set of rules that he thought describe our reaction to technology: Anything that is in the world when you are born is normal and ordinary and is just a natural part of the way the world works. Anything that is invented between when you are fifteen and thirty-five is new and exciting and revolutionary and you can probably get a career in it.
Same sort of thing probably applies to music.
Perhaps asking what a person's favourite tune is can predict their investment attitudes.
We find ourselves shouting exactly the same things to our children that our parents shouted at us "turn that racket off, it's not even music"
This seems to ignore the trend that fewer useful things are invented each year.
