Well, the answer is in Beijing – yes.
I was looking for a certain Nelly Furtado CD and couldn’t find it.
Asked a Chinese friend and he said, can’t find it either but here’s another one for you.
Ok, I opened the CD box and horror! There a piece cut out from the CD. Then I looked better and both the plastic cover and the CD were missing a small square.

I call my friend, no he says, no problem, can play, just try. It’s from the customs people. We are familiar with that. And yes, it’s an original (made in Canada).
OK, expecting my CD player to spit it all out: it played. Just except for the last track.
Don’t ask me for explanations. I am just an electronic engineer.
