title: Python JSON not breaking loop
body: <p>I am trying to use the MusicBrainz API via python and am having a harrowing time trying to figure out why my loop wont break after a certain condition is met. I am passing the duration of a song and the acoustic id via a URL that fetches JSON. I am not sure if the JSON is invaild, but am getting the formatted output to play with. The part where I am stuck is inspite of me telling the code to break when the duration of the song matches the duration of the returned JSON, it still continues to show the rest of the data that matched the duration. Also, I am getting a KeyError for one of the main data elements, which looks good to me! Please help!</p>
  
  <p>Python Code being used:</p>
  
  <pre><code>import urllib2
  import urllib
  import simplejson
  import json
  import pprint
  
  duration = 266
  output = 'AQABz0q6JJFknHgOHH0q9DyQw8lxIzmaLzl6HHyE7yO6G4dP9Mc3JDry4FJR5RfIvccWH0d_PD-O63gi9KTQPjme4-uDxl04hMqcQf0RfXgmKWDSDD8aF9dYTDl5hEPy46gnHY-iPEWZEWfw42
