Although Apple iTunes now has DRM free mp3s available at a premium price, this doesn’t mean that users are now free to share the tracks. Apparently iTunes embeds within the mp3 file details of the person who purchased the track. Theoretically this means that iTunes could report back to Apple that User X’s library includes tracks purchased by User Y.
So, although you can play your tracks freely on other devices, this doesn’t mean you can share them with your friends. I’m sure though, that a utility will appear soon that will remove this information, or at least replace it with dummy details.
