Copy protected AAC audio files were the default format for the iTunes Music Store, using the .M4P extension. In order to play those files with programs and devices other than Apple’s, you will have to remove the Digital Rights Management (DRM) and convert them to the more standard MPEG format, using the .MP3 extension. Apple has since gone completely DRM-free with their music offerings and provide a DRM-stripping service, for a fee. Not everyone is willing hand over more money to the company and luckily you don’t have to. Using the same software used to purchased the protected files, you can re-import them as standard MP3s.
