title: Javascript for native iOS iPod controls
body: <p>Recently, I've found that Google Music's new iOS specific web app (http://music.google.com) has the ability to "hijack" the native iOS iPod's music controls (double tap your home screen and use those pause, play, next, prev buttons while playing Google Music).</p>
  
  <p>I had no idea that this was possible through a web app and have had trouble finding any examples or clues on how to achieve this through javascript. Does anyone have an idea?</p>
