Bought CDs in China, can't play them in the US

[hannum01]

I was in China and bought a music cd and have been unable to play it here in the US. The book was labeled "German 24k cd". I am not sure if I just purchased a cd with nothing on it or if this type of cd doesn't work in the US. Help

Sorry, the CD from China is not a book, but a really nice box with 2 CDs.

Audio CDs do not have any copy protection. It should play anywhere. Can you give more details on what it played on and what it didn't play on?
