I'm currently looking into buying a Plex Pass especially because of the added Gravenote support.
However, I still would like to know what the actual playback experience looks like? When you select a song on a Plex player (say a FireTV, Samsung Smarthub or Xbox One) and just let it play, do you get some kind of visualization displayed on the screen? Maybe something like changing artist pictures in the background that act like a screensaver?
