title: How can I download a song and add it the user's music library?
body: <p>My Android app needs to download a MP3 track and add it to the user's media library.</p>
  
  <p>I haven't found any good documentation on this so I was wondering if it is as simple as storing the MP3 in the Music directory? If so, what would be the location of the user's music directory?</p>
