(Audiophiles) What music do you use to test new earphones?

[Logan]

I use Glitch Mob (they have pretty complex sounds and styles in it that really test an earphone)
What even true instruments (like trumpet, saxaphone, acoustic guitars, true drums, no electronic stuff)
Some dubstep to test the bass
Opera, for testing their vocal capabilites and others.

How about you guys?

first i start with some dub step(i hate it but whatever)
then some classical music lie this: http://www.youtube.com/watch?v=rRgXUFnfKIY
after that i do Dream Theater - Awake album, track#1 (6:00) because it starts with the Drum "cycle" so you can hear the drum and sound stage.
then some music with guitar and a minute of opera.
