The loadStreamUrl command in the playbackSession namespace loads a streaming (live) radio station URL and optionally starts playback. Upon successful completion, the player sends a playbackStatus event to your app or hardware integration. Your app should subscribe to the playback namespace before sending the loadStreamUrl command to avoid race conditions in receiving playbackStatus or playbackError events.

This command requires that your app has an open playback session with a cloud queue, created or joined using the createSession, joinSession, or joinOrCreateSession command.

If you want to immediately start playing the stream, set the playOnCompletion parameter to true. This bypasses the need to send a play command after the player loads the stream.
