Music Stops After About an Hour

On the last few games we have played the music works for around an hour and then stops working and won't play. Any ideas why that could be?

The Music, FX, and Animated gifs in roll20's system behave very poorly the more players, journal entries, page extensions, and proximity to US timezone primetime you get to.  Music fails so much that I have resorted to just using a discord music bot instead.  Sound effects play most of the time though.  FX only behave as they should on the dev server, on production they are laggy and rarely fire when you do them, animated gifs that are not professionally made lag out low end pc's and begin to freeze/pause, animated gifs that are professionally made take longer to do the same problems.  

Also the audio system is only active for the most recently launched session you own.  This is a change made like 6 months ago and is only an issue if you share sessions with free to play folks in discord communities, its why I no longer share(aside from the fact that sharing also causes more performance drain overall to the system).  So if you are hosting a 6 hour session of dnd and your buddy starts a session you shared to him 3 hours in, your audio will suddenly stop working after the current track finishes till you exit the game and relaunch the session, which will be hard to do if your players stay in it keeping it active.  

Thanks for the reply.
