This is the best advice here. Even poor musicians can pick out differences in music with uncanny accuracy. It's always good to start young. I was forced to play the trombone when I about 8, and stuck with it for 9 years. It is a horrible, disgusting, and foul instrument, and I have since moved on to better things.
However, I'm grateful for all the practice I had dealing with different tones and scales. It's very easy to identify notes now, and I know I'll be getting my kids to learn music at an early age as well. As proof of this, I know of no musician that owns Bose or Monster, etc. I've had some of my friends (musicians for a living) try out those headphones at the future shop, etc, and after a few minutes of listening they put them down, and just remarked offhandedly that it does not sound like real music. Consider that they have no experience with audiophile quality headphones whatsoever. That's pretty cool, I think.
