Apple needs to work on putting copy protection onto floppy disks. That worked out quite well before.
Can't Be Pirated is the holy grail of the copyright idiots. It's more important than profit, fame or success. It won't let common sense stand in its way.
The only format that can't be pirated is a format that you cannot listen to. Hey I'm going to encrypt this music and then hand your player the decryption keys! We can try moving the decryption closer and closer to your ears, or to your eyes (as in HDMI), but ultimately it has to interact with your senses and can be picked up using sensors (mics, cameras).
Please tell me again, how many anti piracy measures have actually been effective?
