I know that once people have burned their music to a CD, they could just pop that CD back in and rip the tracks into plain MP3 format, but certainly that is no different (or worse for record companies) than buying a CD and ripping it. Maybe they have some way of dgitally marking the a CD that has tunes that were downloaded from their service so that iTunes won't let you rip it. Maybe each track, when ripped to AIFF form, will have a little noninterfering code that tells iTunes (and the whatever the software that Windows eventually has as its equivalent for the apple music service), not to rip it. Even then, though, there'd be a way to work around it (there always is). This would also not stop a person from burning two copies of a song onto a CD - that is, share their music with friends, but this would be no different from the way people copied tapes... it would not be possible to share songs in KaZaA which I think is the hitch that the record companies are caught up on. Once again, I would not have a problem with this format. It would allow me to do whatever i want with the music... I just couldn't give it away to an absolute stranger.
