Is anyone else having the following issue? Since I have added some stations to Pandora, even though I exit back to the "add new station" screen before exiting Pandora, every time I touch the mute button, Pandora starts playing whatever the last station was that I listened to. This happens even when the device is locked! Very annoying when it's starts playing all of sudden when in my pocket or purse. I can't seem to find a way to stop it other than getting rid of Pandora which I love. Any thoughts????
