Einsturzende Neubauten imports isn't exactly the place I'd expect this stuff 
to have shown up at first, since there can't be all that large a group of 
people who'd want to burn a copy of Blixta & friends banging on bits of metal 
and running jackhammers, compared to say, somebody like britney spears with a 
much greater listening audience

The nasty bit is that these copy protection methods do stuff like introducing 
errors into the bit stream, so that even a standard CD player is trying to 
interpolate data while playing it so you won't notice as much. Apparently a 
CD-ROM drive can't do this sort of interpolation, though it ought to be 
possible in software.

It may be that all the discs coming out of a particular mastering plant are 
being done with this scheme. If it's SunComm MediaCloq being used, it's 
already been cracked, at least for those of us with access to a linux 
machine. I've got the article on how with source sitting in front of me in 
this past fall's edition of 2600 magazine. It can be ordered here for 5 bucks:
