title: How to select random song to play (from the list) on a HTML5 site using JavaScript?
body: <p>My question is really easy, i am just a newbie in JavaScript and i need your help.
  I want to create a site that will select random song, title of it and also its album from a list of sources. I want it to look something like this:</p>
  
  <p><strong>Title:</strong> (song 1 title here) <br>
  <strong>Album:</strong> (album of song 1 here) <br>
  (mp3 player here that uses the source of song 1)</p>
  
  <p>I have HTML code for my player here: </p>
  
  <pre><code>&lt;audio class="audio-element" controls="true" preload="none"&gt;
  
  &lt;!-- Adding audio sources --&gt;
  
              &lt;source src="mp3file.mp3" type="audio/mpeg" /&gt;
  &lt;br&gt;
  &lt;b&gt;Your outdated browser does not support HTML5. &lt;br&gt;
  Get Mozilla Firefox &lt;a href="https://www.mozilla.org/pl/firefox/new/"&gt; &gt;HERE&lt; &lt;/a&gt;&lt;/b&gt;
  
  &lt;/audio&gt;
  </code></pre>
  
  <p>No idea what to do next... Could you guys help? I would really appreciate explaining to me everything you do :) 
  (Sorry for my bad english)</p>
