Specific to the topic post:
A resource that lists CD's that have been deliberately corrupted by their manufacturers
can be found here.General blather on the topic:
Philips is the company pushing for labeling changes to copy-protected CD's. They co-authored the Audio Compact Disc specification with Sony. CD's which have copy-protection invariably do not meet the specification, so Philips says they should not use the official Compact Disc logo or language. IMO, this is absolutely correct - one could reasonably argue that improper labeling of non-standard material as adhering to a standard is, in effect, deceptive practice.
One of the reasons for confusion about copy-protection is the proliferation of techniques - a bunch of different companies trying different methods. Some don't work in some CD or DVD players, some reportedly cause the copied CD to damage stereo equipment when played. I don't have confirmation of the latter - it sounds like convenient disinformation to me.
CD-Mate is a nice program, for many reasons other than those previously stated. Be aware that its CD labeling functionality requires a separate license (the last time that I checked).
Did you know that the music industry gets royalties on recordable CD's (CDR's) sold in the US, specifically to offset the expected piracy of their products? Doesn't matter what the CD's are used for, US buyers pay compensation for crimes they are expected to commit. Surely copy protections mean that they don't need that money any more
