theme music playback on roku

[farside847 39]

I noticed something else that might be a configuration error on my part. In the roku app when you select a movie and land on the movie detail page the theme plays as expected. But then if you press right or left on the remote to bring up the next movie in the list the old theme continues to play. Is there a setting that will tell the roku to play the theme for the new movie displayed? 

Thanks!
