"iTunes downloads each song as an audio stream, but only once it has grabbed the track does it apply the DRM rules - not surprising, perhaps, since the copy-protection coded into a given song is client computer-specific. Technically, then, PyMusique doesn't bypass the copy-protection code since it grabs the file before the DRM rules are applied. Still, it's a moot point and one that lawyers will enjoy debating if they're given the chance."
Whose goofy idea was that? Windows Media is better - it downloads encrypted files from the get-go. In fact, you can share them with your friends. If you go to play a file you got from your friend, you are taken to a web site where you can buy the key to unlock the track.
