When the Chromecast first came out in late July it connected to very few things. You could cast YouTube, Google Music, Google Movies and Netflix. Hulu Plus was added in mid October. Today Pandora has been added to Chromecast.
It works great on my HTC One which is an Android phone. The icon shows up at the bottom and it works exactly like all other Chromecast enable app. It also works on the iPad. However I did run into a glitch while trying to run it on my iPad mini. First it took me some time to find out where the icon was, if you tap on the volume button it is right there next to the Airplay button. Like the Android device the iPad version connects perfectly and starts playing and you can control everything on the iPad. The problem came when I was trying to disconnect Pandora from Chromecast. On my HTC One you simply hit disconnect and it stops casting. On the iPad there is no disconnect button. I tried to switch to iPad as my choice, but it continued to casting to my TV. Then I started to play a different song on the iPad but the older song continued to play on the Chromecast. The only way I could get it to stop casting was to start YouTube and cast that and then disconnect. I suspect that this is something that will be fixed in the next update. Other than this glitch it works great.
If you are a Pandora user and don’t have a Chromecast I recommend getting one. I think it adds value to the Chromecast, which in my opinion already was well worth the $35.00 I spent on it. Being able to play Pandora through my big screen TV which is connected to my full sound system and control it on my tablet or phone is great.
