"You're Listening to iTunes Radio" error
After changing the password for my Apple ID on my iMac, I am unable to sign in to iTunes Radio from any of my devices (iPhone 5S, iPad 4th gen, or Apple TV 3rd gen). While surprised the devices didn't just learn my new password, I assumed it's perhaps a security matter so have been attempting to sign in with my new or old password. Most everything else appears to work. But when I attempt to listen to iTunes Radio, all I get is a male voice repeating over and over continuously "You're listening to iTunes Radio." On-screen the display just cycles through album covers. I was able to listen to my own music streamed from iMatch on my iPhone, but not my iPad, and neither plays iTunes Radio--just that "You're listening to iTunes Radio" repeated over and over. I have tried power cycling the iPhone, turning iTunes Match off then on, entering my iCloud ID in lieu of my normal non-Apple domain Apple ID, all to no avail.
I had no idea updating my Apple ID's password would be so problematic. Can anyone help me or has iTunes Radio simply gone crazy?
