title: How to update a playlist using SoundCloud api wrapper for java
body: <p>The soundcloud documentation has no sample for updating a playlist using java wrapper. I tried something like this but it didn't update the tracks. And no error messages returned.</p>
  
  <pre><code>HttpResponse resp = wrapper
    .put(Request.to("/me/playlists/123")
    .with("playlist[title]", "updated title", "playlist[tracks]", "[
      {id: 10001},
      {id: 10002}
    ]"));
  </code></pre>
  
  <p>Any ideas?</p>
