Just found a page dedicated to Corrupt CDs. What are "corrupt CDs"? To borrow the description from the site (with my emphasis):
1. Prevent you from copying it for personal use or from playing it on computerized devices (computers, DVD players, game consoles like PlayStation, MP3 players, consumer CD duplicators, high-end stereo equipment and car CD players).
2. In the United States, Canada and the UK, these "copy-protected" CDs are unmarked. Once you buy it, you can only exchange it and hope that the replacement isn't garbage too.
