As an audiophile with a pretty good system, I will admit that I like to listen to rap on my own system. I also listen to electronic, classical, classic rock, rock, bluegrass, Norah/Allison/etc..., pop (for lack of a better descriptor), latin, southern rock, blues, jam bands, funk, jazz and others that defy category. I am 23. I believe your system should sound good with all types of music, unless you can have more than one system to handle different types of music. Because my own tastes are so varied it is hard to recommend something for auditioning for everyone. My suggestion is therefore a CD that they are familiar with. Then they can hear the difference.
