Tips and warnings
The Apple iTunes Store no longer sells protected MPEG4 files, but many music libraries still contain remnants of the old model. Although the .M4P format may have been a good idea in the past, they were not right for all users. If you want to play your protected music with other media software or on a personal music player, converting your files to .MP3 is a good option. Changing your .M4P files to .MP3 is easy on a Windows operating system as long as you know what you are doing.
