Yes but the thing is, leaving the tv on just to listen and not watch would effect the tv's longetivity as well as the brightness would actually be less the more hours one puts in it. With that said, I sometimes keep the tv on and fall sleep on it for hours at a time even pausing the video.Newer tvs have technology to avoid burn in. It can still happen but it's not likely. I don't use Pandora so can't say anything about that but the music channels have an image that moves around so it doesn't get burned in.
