nanofever has posted two ways around the copy protection which basically point out what the real problem with making copy-proof PC media. If your computer can read it, can store it in memory in a usable form, then it can also be made to write it somewhere else. Think about it, your computer is really based around making very simple binary calculations and copying data from one place to another. Once you load something into memory it is extremely hard to keep people from doing whatever they want with it.
The glaring problem I see with this protection method is that they are introducing snippets of noise. Noise that is wildly dissimilar to the music you are trying to listen to, so wild that it is filtered out by the player itself because it assumes it has made an error. What I would see happening is someone ripping the original data onto a hard drive and munching it with an audio decoder which will filter out and interpolate a high-quality bridge for all the sections which are obviously ass. Tada! Not only do you now have a burnable CD, but there is no copy protection left!
