Random song won't work with albums

When using the random_song parameter the current implementation will always call user_playlist_tracks(uri) regardless if a playlist or an album was provided using uri. Consequently the call will fail for album uris like 'spotify:album:5wuthq3XXmrpwlowdNxsBf' and execution will stop.

Quick fix I did for myself:

           if random_song:
                if uri.find('album') > 0:
                    results = client.album_tracks(uri)
                if uri.find('playlist') > 0:
                    results = client.playlist_tracks(uri)
                position = random.randint(0, results['total'] - 1)
                _LOGGER.debug('Start playback at random position: %s', position)
                kwargs['offset'] = {'position': position}

Btw, user_playlist_tracks() is deprecated, that’s why I changed it to playlist_tracks().

Thank’s for your great component!

Thank’s for pointing me into the right direction! I’ll have a look, however, after your explanation it seems pretty clear anyway…

First, the flow that HA is using doesn’t matter as all flows can get you a token with the selected scopes (list available on the spotify developer site, this list lacks the one that is needed to start chromecast on an idle cast device. The name of this scope is gone from my memory but I have it somewhere)

The token you receive using any of the flows lacks a scope to start chromecast on an idle chromecast device. It will be powerful enough for connect devices as well as play something on an already started spotify app on chromecast given the app was started in the same account (by for instance an official spotify app)

You can try this yourself if you want by using your token you received and a standalone pychromecast checkout. In pychromcast there is a spotify example. Modify it so it takes your token instead of the scraped token and make sure your chromecast device doesn’t have spotify running.

You will hear the bloink when spotify starts on the device but it will fail after the token is sent to the device.

When I spoke with the team responsible for cast at spotify they were clear that they only let themselves and google have this capability and did not plan to let API users have access to this capability. Since then there are a few more commercial integrations that has been granted this bit they are still a very select few.
