I, too, think that the music is overpriced but still I'm willing to pay for the tunes I really want to listen to. I'd just like to be able to listen to the purchased music on all my devices, without paying for each new format invented. If I have to pay for each format/device then I'd rather choose to stop listening to new artists alltogether.
For people like me all-DRM world is an end to our already limited freedoms. Being technically able to download mp3s from the Internet doesn't automatically mean I want to go this road. Maybe I'm just a sheep in the pack but I'd love to remain a peaceful law-abiding self.
