iTunes M4P Music
M4P is the Protected AAC File. AAC is the audio layer from the follow-on format to MP3. The .M4P extension is AAC purchased from Apple's Music Store and is protected by a Digital Rights Management scheme. MP4 files encrypted by FairPlay DRM as sold through Tunes Store use .m4p extension. M4P is for the DRM protected content in iTunes Store, while m4a is for the DRM-free, unprotected content.
iTunes: Owned by Apple, the iTunes store set the pattern for a la carte music shopping and still reigns king over the customer base. iTunes has sold more than 5 billion songs to date, and it offers excellent integration with the world's best-selling MP3 player, the iPod. It's catalog contains more than 8 million songs as well as a variety of podcasts, TV shows, and movies. The one major bummer is that most of the tracks sold in iTunes can only be played on the iPod or iPhone and not any other MP3 player. You must download the iTunes software in order to access the store, but it works on both Windows and Mac operating systems.
eMusic: This indie representer is quite a ways behind iTunes in catalog numbers and sales, but it controls the second largest market share (10 to 15 percent, according to label feedback). eMusic has sold more than 200 million tracks in the past four years and is currently averaging five to six million song downloads per month from its catalog of over 3.5 million tracks. The company made a name for itself with an all-you-can-download service but now offers limited subscriptions, starting at $11.99 per month for 30 unrestricted MP3s. Thanks to this "track pack" pricing and the fact that the company doesn't currently sell big label songs, eMusic offers an incredible value: it is the cheapest of the bunch by far (27 cents per track with the Premium plan). It also has a large number of music reviews by editors and users alike.
An MP3 file is made up of multiple MP3 frames, which consist of the MP3 header and the MP3 data. This sequence of frames is called an Elementary stream. Frames are not independent items ("byte reservoir") and therefore cannot be extracted on arbitrary frame boundaries.
