title: How to list all media in Android?
body: <p>I'm building a specialized media player for android and need a way to select a song from the device.  I like how the builtin music player groups everything by artist/album, is that something I would have to write or is there something I can just plug in to get that functionality for free?  </p>
  
  <p>What is the easiest way to list music files on the phone with some basic grouping by the idtag info?</p>
