title: Can't Connect to Facebook Based Spotify Account
body: <p>I'm using the Pyspotify Spotify client. In order to connect to a session, they supply a class <code>SpotifySessionManager</code>, which takes <code>username</code> and <code>password</code> parameters. However, I and many people connect to Spotify using Facebook, and once you have done so Spotify does not provide a way to get a more traditional user name and password. Any Pyspotify users know how to work with this common form of Spotify user authentication? </p>
