Natalie Imbruglia's new album is the first to be released with a system that stops it being copied.
It means pirate copies can't be made but also that you can't play these CDs on your PC, DVD or transfer it to Minidisc.
So is this a good way to beat the pirates - or will it change the way you listen to your music?
Here's what lots of you have been saying.

I think that although it's good that it stops pirates, it's a bad idea because people like me who have an old CD player or a computer to play their CDs.

I think that CDs should be made pirate proof because pirates cheat the artists out of their hard work.

I think that if the music companies are so bothered about pirate CDs then they should be having the war with the mp3 and CD burners manufactures not with people who download or burn CDs because they are the ones making the profit.

I don't think it's right to put a ban on copying CDs. Anyway Natalie Imbruglia isn't that big a star so why would people want to copy her CD anyway!

I don't think the CDs should be copied proof
as some people won't buy them if you can't copy them for your friends.

I think they should make CDs pirate proof because people will want to copy big bands CDs and sell them cheaper so people will buy them.

I don't think that CDs should be pirate proof because that means some people won't bother buying the CD because you can't play the cd on your pcs.

I think its the manufacturers fault in the first place that CDs are being pirated. If they weren't at such a high price then people wouldn't copy them because they would then be at an affordable price.
The copy protection doesn┐t really work. You can still download the album - my dad found it in 2 minutes no problem. If they want to stop piracy they should make CDs cheaper like they are in the rest of Europe and the USA.

I think it is a good idea, but some people might only listen to music on their DVD or PC so it isn't a good idea as well!

I think that CDs for big bands should not be made copied proof because the bands do not need the money. Whereas small upcoming bands do so their CDs should be made copy proof.

I think that CDs should be cheaper so nobody bothers to make pirates.
I think everything should be done to stop pirates, because in the end it makes our CDs more expensive.
