Edit iPhone Music ID3 Tags From App

I'd like to develop an iOS app that fixes tags in the user's music library 开发者_JAVA百科using MusicBrainz. I haven't been able to find anything in the official SDK to facilitate the changing of ID3 tags for the song library, so I'm wondering if I missed something. Or does Apple even allow an app to behave like this? Any help would be appreciated :)

Well , as you know , Apple is pretty strict when it comes to messing up with their data. iPod library can only be altered via iTunes syncing or iTunes downloading.

I hope they will give us programmers ways to (at least) create playlists , but until then , you could only accomplish that by jailbreaking and using private API's.
