Music to DH ski with

Lately I've been doing a few runs to music with an MP3 player and headphones in my helmet. Tull's Thick as a Brick and Jesse Cook's Vertigo are the top of my list for music to accompany GS cruising, bumps, and steeps. Parts of Dark Side of the Moon work well for powder skiing. A good paced beat with some energy seems to work best in general for me.

I was interested to hear what others who DH ski with music listen to while skiing.
