Once I add this route this is one of the errors I receive in console:
XMLHttpRequest cannot load http://developer.echonest.com/api/v4/artist/search?api_key=%3C5HDKQ6LW5CWJS…&bucket=hotttnesss&bucket=biographies&bucket=id:musicbrainz&name=snoop+dog. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:9000' is therefore not allowed access. The response had HTTP status code 400.
