I wonder is that sound I heard earlier today was a vein bursting down at stupid-central (otherwise known as the RIAA) - Amazon has a pretty clear statement on DRM on their "how to rip a CD" page:

Many of our customers have already figured out that one cheap way to get DRM-free MP3 files is to buy them on CD and rip them themselves. Luckily, we offer everyday low prices on many terrific titles to help you stock your portable player. For those of you who haven't yet dabbled in ripping your CDs, we've created this handy ripping guide that takes you through it. It's quite easy, and if you own a portable music player, it's a legal, cost-effective way to fill it up.

On the other hand, Amazon doesn't seem to hate their customers. I can't really say that about the music labels...
