title: How to make a private track public using the Soundcloud API?
body: <p>I can't seem to find a way to edit the <code>&lt;sharing&gt;</code> attribute of a track.
  Is it even possible ? </p>
  
  <p>If not, can you suggest a way to schedule the release of a track ?</p>
  
  <p>Thank you very much</p>
