M4P - MPEG 4 protected audio, is a protected AAC file extension, generally used by Apple iTunes purchased songs with DRM (digital rights management), while M4A is an audio extension for unprotected AAC file. That’s to say, both M4P and M4A are AAC files, but M4P is DRM protected while M4A is DRM-free.
Aside from your old songs bought from iTunes Store before April 2009, all Apple Music files are in protected M4P format. Due to M4P files cannot be played and transferred to any other unauthorized computers, any MP3 players but only your iPods touch, iPhones and iPad (most 5 devices), many people want to convert the protected M4P to M4A.

Once the iTunes Music Store launched we saw the introduction of "Protected" AAC files (.m4p). These are the files types that were originally sold on the iTunes Store that had DRM (Digital Rights Management) copy protection in them.
In 2007, Apple introduces "iTunes Plus". iTunes Plus refers to songs and some music videos* in high-quality AAC format that don't have Digital Rights Management (DRM). The file extension associated with songs purchased from iTunes Plus is .m4a.
In 2009, Apple finally allowed you to upgrade the protected AAC (.m4p) to iTunes Plus in DRM-free M4A format. An individual track upgrade costs 30 cents, or you can choose to upgrade your entire purchased protected music. However, this option quietly disappeared when Apple announced a suite of iCloud-linked music services in 2011.
In 2013, Apple introduce iTunes Match. iTunes Match scans your iTunes music library. Once the scanning is complete your music is available to you on any iOS device. You no longer have to sync the music files from your Mac to your phone. And you don’t even need to keep local copies of the files on your Mac if you don’t want to.
It costs $25 a year. But for the $25 you get another bonus. Since all the music in Match is iTunes Plus (DRM free) you can convert your m4p files to m4a by simply forcing a re-download of the files. Once you do that you can upload them to Amazon Prime, copy them to your Android tablet, etc.
If you subscribe to iTunes Match, you can download your previously purchased music (M4P files) again in the iTunes Plus format (M4A). To do so:
1.You need to delete the original DRM song from your library first. Doing this enables you to download the song again in the iTunes Plus format from iTunes in the Cloud.
2.Click the Purchased tab in the iTunes Store.
4.Locate the artist of the song you want to upgrade.
5.Click the iCloud Download icon next to the song you want to upgrade.
Compare method 1 and method 2, you'll find that method 1 is far easier than method 2. Apple Music Converter can not only remove DRM from the old iTunes songs, but Apple Music files and Audible AA/AAX files. Though it is not a freeware, but it is cost-effective. Download it and change the annoying M4P to M4A now.
