Query: CD is corrupted by copy-protection!

Beware if you listen to your music on portable devices and computers. The CD I received in September 2003 was corrupted by copy-protection, preventing it from being copied to portable (MP3/WMA) devices. It would not even play on any of my four PCs as a standard audio CD. Amazon does not indicate the CD is corrupted as such, even though the recording company does indicate this in small print on the back cover. I am returning my copy, since it does me no good if it only plays on an old 20th-century consumer CD player.
