Music to evaluate Speakers and System

Female Jazz is fine but that music sounds good on almost any speaker, I swear some must love the format simply because it makes them feel good about the gear they own.
You only need to bring what you like and are familiar with to decide what you like.

I would agree to bring a poor sounding recording to see how the speakers will play new music, Rock and Pop are some of the worst offenders so beware of how a speaker handles this music if you enjoy it.
