I think all this copy protection is a bit of a wank.
There is no way to stop piracy and there NEVER was. If theres a will theres a way and its usually pretty easy too (as demonstrated each and every time). Vinyl, tape, cd, its always easy to copy.
I wish record companies and kunts like the RIAA would stop whining about lost sales because of pirating. Lets face it, if people don't want to buy music, they won't and you can't force them to either. There are too many factors involved.
Just keep the format simple, easy to operate with, realistically priced to manufacture and make sure you put GOOD music on it.
