re: What song do you use to test the sound quality of new sound equipment?

Below is the playlist I made a couple years ago when auditioning headphones. Good for speakers, too. I included some tracks that have been known to make my ears bleed due to shrill-sounding female vocals or saxophone. For my home system, this was tamed by running MCACC on my Pioneer Elite AVR. For headphones, I moved to another set. Besides highlighting her spectacular voice, the Sara Bareilles track has some piano chords near the end that completely fell apart into disorted mush on some headphones I tried.
