Where should I buy music online?

This is related to the post about Brett Dennen. I want to buy his songs. I am willing to pay a reasonable amount per song (which seems like it is universally accepted to be $.99), and I'd like to buy from a minimally evil company. If the company stands against DRM, this is a plus. If the company doesn't donate large quantities of money to the Republican party, this is also a plus.

Edit: The executives at Yahoo Music seem to have a clue.
