title: SoundCloud Api - How to show playlists in favorites
body: <p>is there any way to get sets (playlists) I marked as "like" from /users/userid/favorites ?</p>
  
  <p>It seems that "/favorites" only shows tracks and no playlists? Maybe there is another way to check if a playlist was marked as "like", but I did not find anything usefull.
  The SoundCloud-Android-App can handle this situation, but maybe it's not using the developer API.</p>
  
  <p>Thanks in advance.</p>
