title: Using Mutagen to process all accepted file types
body: <p>What do I need to do in order to process every file type accepted by mutagen, .ogg, .apev2, .wma, flac, mp4, and asf? (I excluded mp3 because it has the most documentation on it) </p>
  
  <p>I'd appreciated if someone who know how this is done could provide some pseudo-code in order to explain the techniques used. The main tags that I'd want extracted are the title, and artist of the files, album if available. </p>
  
  <p>Where to start?</p>
