This is such an important flaw in all DRM. At some point all this digital wonderment has to be turned in to light and noise. This is the weakest point in the chain and it only takes one person with a decent re-recording setup to create a copy and then distribute it for any DRM to be bypassed. A £50 mic setup in a home studio will allow a good enough copy of most pop music to be made. Even if the hardware was in on the DRM game (looking at you Apple), my ears and eyes are not.
