I'm using a Samsung Prevail LTE and I am too getting the "Listening for TV" thing. I tried having the phone right next to the TV set, nothing. Plugged an auxiliary audio cable (I'm in a commercial truck while watching this.....no, I'm not driving, the truck is parked at a truck stop), and it's still Listening for TV. The parks blog seemed to indicate the app should interract with ALL the major musical segments. Hopefully it'll work during the fireworks show? Edit: Nope, never changed. Always said Listening for TV. :-(
