Music tracks for tweaking

I have monitors and powered subs with built-in cross-overs. After burning-in new speaker cable, the cross-over point needed to be adjusted. There’s a clean kickdrum solo opening “I’m So Aftraid” on Fleetwood Mac’s ‘Dance’ CD. These few beats were great for dialing in the cross-over point and volume. Now, the kickdrum sounds tight & resonant w/o being wooly. This adjustment seems to work pretty well across-the-board for all music.

What other music tracks might you recommend for tweaking - whether it be midrange, high or low frequency? Also, what hidden musical cues within songs have you discovered. One example might be is a certain percussive note a bell or a triangle. With Tidal’s vast library, there’s opportunity to see how resolving our system’s are.
