body: <p>If, for example, I only want to play a song at index 3, 5, and 9 in media library, how can I do that?

  <pre><code>private SongCollection mySongCollection;
  </code></pre>
  
  <p>Can I perform something like this:</p>
  
  <pre><code>mySongCollection = library.Albums[index].Songs + library.Songs[index];
