Soundcloud API - Find Playlists that Contain a Specific Song

After exploring, and experimenting with SoundCloud's API - it's not possible to find what playlists contain a certain song...

However, SoundCloud uses a simple URL format to show which playlists contain certain songs - http://ift.tt/1HFdrec

For example: http://ift.tt/1Vmvld0

Is there any way to scrape the playlist IDs off a web URL such as the above? I've tried to curl the page and it doesn't give the IDs of the playlists.
