you may not be familiar with this episode - they tried numerous methods of DRM'ing CDs. Some were circumventable with black marker. http://en.wikipedia.org/wiki/Sony_BMG_copy_protection_rootki...


I was, but none of those methods even came close to working; you could "circumvent" them just by putting the CD into a computer running an unexpected operating system, because they all had to be compatible with existing CD players.
