title: How play a .mp3 (or other) file in a UWP app?
body: <p>I try this:</p>
  
  <pre><code>PlayMusic = new MediaElement();
  PlayMusic.AudioCategory = Windows.UI.Xaml.Media.AudioCategory.Media;
  
  PlayMusic.Source = new Uri(@"C:\Users\UserName\Desktop\C:\Users\user\Desktop\Kill The Alarm - Begin Again.mp3");
  PlayMusic.Play();
  </code></pre>
  
  <p>No more error messages appear on the display (try catch runs clean through).</p>
  
  <p>Sorry for the short description...
  I can read and understand English very well but it is difficult for me to talk and write.</p>
