 <p>Do you mean a short url something like this: <code>http://snd.sc/abc123</code>? If so, could you include the request which gives you that short_url? Otherwise if it's a 'normal' url like <code>http://soundcloud.com/username/track</code>, you can use the <a href="http://developers.soundcloud.com/docs/api/resolve" rel="nofollow">resolve endpoint</a> to get the track (or user, or set, etc) data.</p>
