什么是 M4P？
M4P is the iTunes Protected AAC format, used by Apple for DRM-protected music purchased from the iTunes Store before 2009. It uses the MPEG-4 Audio container with Apple FairPlay encryption wrapping AAC-encoded audio. Unprotected M4P files (after DRM removal) can be converted to standard audio formats.
