title: Force download mp3 for mobile site on iPhone
body: <p>I'm working on a little mobile site for a musician and they want to be able to let users download a song for free on their mobile device. The problem I'm running into is that in Safari for iPhone the song plays in the browser no matter what and does not get added to the music library.</p>
  
  <p>On Android I've been able to force a download which the user can then add to their music application of choice.  I was hoping there was some way to get the song into the iPhone music library with out requiring some additional application or going through iTunes.</p>
  
  <p>Any help would be greatly appreciated. Thanks!</p>
