I have test tracks for imaging and blahblkhablah but for listening purposes I really like club/dance music:
Dj kaycee escape (original mix) has a mix of everything in it. Its fast its slow, it goes high it goes low. bumps so hard my tires blow hahah...sorry..
but seriously to test your system you really should play some classical music. I really enjoy Bach and motzart personally but there are tons of others. The bass..is there trust me.
