WP7 Music+Video hub integration possibilities

Is there currently a way for my WP7 app to:

1. Scan for available audio files, that have been transferred to the phone via Zune?
2. Start a playback of a selected audio file from within my app's UI, but still have an ability to "record to a file" the point, at which the playback was ended (or paused), so I would be able to allow the开发者_如何学JAVA user to resume at the same point?

1. You can use the MediaLibrary to find the songs/albums that's available on the phone.

2. You'll use the integrated player for playing music, so if the user pauses the play, the user can simply use the standard music interface to resume play. It's not the task of your application.
