In the meantime I'll be buying and downloading from Amazon's mp3 store.
Me too! I just found my way around that site. It's not pretty, it's a lot less logically laid out than iTunes, and making changes to your Account Details there is unnecessarily complex.
But it's cheap, you can buy single tracks that iTunes won't sell you unless you buy a whole album, and the quality is fine. So now I have two places to buy, and if iTunes plays up, well... there' still Amazon, lol. 😉
