Plugin to return to previous stream?

Is there a plugin that will return to the previous stream/playlist that was previously playing - a bit like the 'previous' button on a TV remote?

Scenario is, I'm working from home listening to a playlist or stream (Spotty), and then flick over to a radio stream to listen to the hourly news. It would be great if I could click one icon/menu item to return to the previously playing playlist/stream.

As it is now I need to head back to the home menu and drill bak down into either favourites or My Apps to restart where I was.

Thanks,
Dean.
