title: Spotipy (Spotify's Web API Python wrapper) examples failing
body: <p>I cloned and installed Paul Lamere's <a href="https://github.com/plamere/spotipy" rel="nofollow">Python wrapper for the Spotify Web API</a> via <code>python setup.py install</code> but I can't seem to run some of the examples correctly.</p>
  
  <p>Specifically, when I try to run <a href="https://github.com/plamere/spotipy/blob/master/examples/user_playlists_contents.py" rel="nofollow"><code>user_playlists_contents.py</code></a> or <a href="https://github.com/plamere/spotipy/blob/master/examples/user_starred_playlist.py" rel="nofollow"><code>user_starred_playlist.py</code></a>, a browser is launched and I'm directed to the Spotify login page. After logging in, I get a Spotify error within the browser that only says: "Oops! Something went wrong." The script asks for the URL I was redirected to, but entering in both the URL of the login page and the URL of the error page (obviously) trigger an error within the Terminal: <code>spotipy.oauth2.SpotifyOauthError: Bad Request</code></p>
  
  <p>At first I was using a Facebook-connected Spotify account and logging in to Spotify through Facebook when prompted, so I thought that might be an issue. However even after creating a new email-only Spotify account and running the scripts on this new email-only username I got the same results.</p>
  
  <p>I also tried registering a new App in my Spotify developer account and using its <code>CLIENT_ID</code>, <code>CLIENT_SECRET</code>, and <code>REDIRECT_URI</code> in the <code>examples/util.py</code> but this didn't seem to do anything. It seems unlikely anyways that modifying <code>examples/util.py</code> is necessary.</p>
  
  <p>Thinking this might be a browser issue I also reset my browser (Chrome) and after that didn't work I tried switching Safari to the default browser but that also did nothing.</p>
  
  <p>Both these scripts depend on <code>prompt_for_user_token()</code> which is defined in <a href="https://github.com/plamere/spotipy/blob/master/examples/util.py" rel="nofollow"><code>examples/util.py</code></a>, and seems to be where things are going wrong.</p>
  
  <p>What am I doing wrong? Have I missed something painfully obvious? Thanks in advance.</p>
