/*
* I haven't found a direct way of extracting the download URL of a Mixcloud track.
* Mixcloud's track preview URLs and full download URLs are similar. The preview URL for
* a Mixcloud track is simple to extract.
*
* This method replaces the "previews" part of the preview URL with "cloudcasts/originals" and then
* cycles through all of Mixcloud's stream servers until the download URL is found.
*
* Similarity between Mixcloud preview URL and full download URL:
* http://stream8.mxcdn.com/previews/9/6/a/e/93a8-2d77-4573-85c5-68bfb679d9bc.mp3 - preview URL
* http://stream11.mxcdn.com/cloudcasts/originals/9/6/a/e/93a8-2d77-4573-85c5-68bfb679d9bc.mp3 - download URL
