I've just bought for my wife what purports to be a Compact Disc of a well-known band's latest album. I didn't download the tracks from the web, borrow the disc from a mate or in any other way illicitly acquire the music - I paid money over the counter and bought the CD.
The trouble is that it's not really a CD. The label states that it's playable in any home CD-deck, but not in a PC or other types of playback machine such as our in-car CD player. All of these machines bear the official Compact Disc logo,but significantly the jewel-case and label of the new album - published by the BMG group - do not.
If it's sold as a CD, then all machines capable of CD playback should be able to play it, otherwise it's not a CD at all, but some other copy-controlled format. It's very tempting to return this disc as not fit for the purpose for which it's been sold and if I can't get round the protection, that's what I'm likely to do.
