How do you turn off itunes radio on your tv when using Apple TV?

Can you elaborate on the issue?

So you're listening to iTunes on Apple TV. When you leave iTunes it will continue to play your selection.

You can search other places like "Movies" or "Trailers" while continuing to listen to iTunes.

Select something else in "Movies" or "Trailers" for example to watch or listen to; then ITunes will stop automatically.

You can then exit that, and iTunes will remain unselected and play no sound.

The iTunes gives you the option to brows other stuff while listening to it.

In my prior post "iTunes" refers to "iTunes Radio."
