These are some tracks I use to test out components, speaker positioning and sub integration. You may or may not like all the music, but that is not the point.
Like Someone in Love, Diana Krall - bass balance for sub integration. I know how the bass should sound relative to the mix.
Girl in the Red Dress, Greg Karukas - The keyboard should be ridiculously big. A good indicator that the system can soundstage and cast a image beyond the speakers.
Lineage (Lenny's Solo), Return to Forever, Returns Live - A great track to see how "tunefull"your system's bass is.
Papa was a Rolling Stone, Superbass 2 - If this track doesn't make you smile something is wrong.
The Boy is Mine, A-capella Remix, Ariana Grande, Brandy and Monica - you should be able to differentiate the vocals - Besides it proves that some pop singers have talent if you strip away the "pop machine."
Basic Drummer Free Improvisation, Jim Keltner, Shefield Drum and Track Record - Just an awesome test of you systems capabilities, keep one hand on the volume control the first time you play this one.
