iTunes Store and m4p File Extension

Since iTunes Store launched on April 2003, it has become the most famous software-based online digital store. On the iTunes Store, individual songs were sold for the same price with no subscription fee.

Musics in iTunes Store are in the protected AAC format, called m4p file extension. File extension m4p is fairly new, which is an audio format that is purchased from Apple's Music Store (iTune) and is protected by a Digital Rights Management scheme. File extension m4p has smaller size than mp3 with equal quality. .m4p file format was created by Apple to protect .m4p files from illegal distribution.

Once you buy a music file in .m4p format, you can play them with most media player; iTunes, QuicTime, Winamp, RealPlayer, Media Player Classic or others. If Windows is unable to play this file extension m4p, you may need to install apropriate player or may have registry errors. To solve this problem, simply install the applications above and/or scan your registry for errors.

Though there a lot of media players support .m4p files, you can only play it in limited numbers of portable media. In the past, file extension m4p only playable on few digital music players that is support .m4p files. Fortunately, now available song in iTunes Store sold in iTunes Plus song. iTunes Plus songs are free of burn limits and digital rights management (DRM). So the musics your buy from iTunes Store you can play it on iPod, Apple TV, Mac and WIndows computers, and more media players.

As the music in iTunes is encrypted with DRM, you cannot directly put it on any non-Apple MP3 player. The easiest way is:

1. Insert a CD-R or CD-RW disc into your CD-ROM drive.
2. Burn your playlist to make an audio CD.
3. After the audio CD is successfully burned, insert the disc into your CD-ROM drive again. Then you can use iTunes to import the music tracks on the burned disc as MP3 files.

Or you can get some software to help you. I use TuneClone M4P Converter ( http://www.tuneclone.com/m4p-converter/ ) to do this. Though not free, it is very well worth a try. It generates a virtual CD drive to help to remove DRM from iTunes.

@dudude: Thanks dudude, your tips works! though recompressing digital song file will reduce its quality. Fyi, by April 2009 Apple has announced that DRM has been removed from all songs available on iTunes Store. Apple named that DRM-free songs as iTunes Plus.

@viss-blog: You're welcome..
@clarkvanhorne: Basically the only difference between iTunes plus video and older format is that iTunes plus is DRM (Digital Right Management) free with equal quality. iTunes Plus music and video can be burned to CD as many times as you need, synced to any AAC-enabled device (such as iPod, iPhone, or Apple TV), and played on any Mac or Windows computers you own.
