title: Google ClientLogin Authorization and Google Music
body: <p>I am playing around with Google Music. I'm trying to see if I can write an app that will stream my music files uploaded to Google Music. So far, I've managed to authenticate myself using ClientLogin and access the music.google.com page. However, whenever I try to access <a href="http://music.google.com/music/services/loadalltracks" rel="nofollow">http://music.google.com/music/services/loadalltracks</a>, the page that contains all of my tracks in JSON format, I get a 401: Unauthorized error. However, if I pass the cookies containing SID and HSID, it works and I can access the page.</p>
  
  <p>Does anyone know why It doesn't work with ClientLogin, outside of Google not supporting it with Music? Have you had similiar experience with other Google Services? In the event I can't get ClientLogin to work, is there anyway to work around it, using the SID? I don't know how the HSID is generated.</p>
