Whatcha listening to?

Update:Winner! Sharon Svitak! Email me with your addy. :) Original Post: I have a $15 iTunes gift certificate, and here's what I want to know. What are you listening to? My hiking music list needs an update. I let the teenagers upload me some of their stuff . . .

It was very nice of them, and it's nothing personal, but their music hurts my brain and threatens to shake the fillings right out of my head.

So I'm asking you. Whatcha listening to? What must I have?
