I am trying to get the list of albums from a user's library. The user is able to successfully login but the albums property of the library object is undefined. How do I get the list of albums for a user?

music.authorize().then(function() {  
        music.api.library.albums.then(function(cloudAlbums) {
                    // user's cloudAlbums
                    console.log('cloudAlbums');
        });
   });
