I think no patch will ever work for Chromecast because Chromecast uses chrome to connect to Pandora. At that point, the Pandora app becomes a glorified Pandora remote for the chrome web browser. Cast something to the Chromecast, turn off Wi-Fi and watch the Chromecast keep playing audio even though the android device is not on the network. For kicks, reboot your android device and watch Chromecast still play music autonomously.
