How to save song/mp3 to Media Library in Windows Phone 8?

Question

I'm solving simple task - in Windows Phone 8 it should be possible to save mp3 file downloaded from Internet into phone Media Library, not just into Isolated storage. Hint for the API is here:
What's new in Windows Phone SDK 8.0
The only thread about this problem I have found:
MediaLibrary SaveSong method

Is anywhere simple guide how to save mp3 song into phone Media Library or at least MSDN article describing the MediaLibraryExtensions.SaveSong? Thanks!
