title: auto pause mediaelement.js audio player when playing new track
body: <p>using the mediaelement.js audio - Does anyone know how or if it's possible to have 1 track pause automatically when another is played when there are 2 or more audio tracks on the same page? (I guess like a play/pause toggle attribute) </p>
  
  <p>there's an example of what I'm talking about here using a flash player: <a href="http://stockmusicboutique.com/background" rel="nofollow">http://stockmusicboutique.com/background</a> but was wondering if it would be possible with this html 5 player.</p>
