Some albums are now available on itunes as "itunes plus", meaning they have no copy protection and are 256 kbps...they're $.30 more, though. To get them to show up you have to go into your profile and check a box that says "show itunes plus".
Or you could just wait a year or two
...Steve Jobs really wants iTunes music to be DRM free since that's what the consumers want...but the music suits do not, of course.
