There's a good chance when you buy music from the iTunes Store that the files that you download will be copy protected by Apple's FairPlay DRM system. It's a great system that protects the rights of the artist and publisher by making it difficult for the consumer to distribute copyrighted material. However, DRM can also be very restrictive by stopping you playing legally purchased music on your MP3 compatible hardware. So, what happens if you want to play your DRM'ed music on a non-iPod?
