I've done it quite easily, I used an old credit card (much thinner than the CD would be) but stiff enough to do the job. Just carefully start at one end and ease very gradually at the corners, you should find it coming loose bit by bit. Work your way along ( don't rush it, or you'll snap it) after cleaning, just reapply new silicone two face tape to the back of the emblem. Of course you will then have to shape it around the numbers with an Exacto knife or likes. Leave the tape backing on until finished. Easy does it, good luck.
