Plex Won't Play Music on Smart TV

So, just some additional info. based on logs I see, looks like the server side thinks it’s now looking at a video type of item (its a FLAC song in a queue on the client) – which I suspect the client can’t play (obviously). See the logs below for the attempt to stream the next song (this is the first set of logs after playing a successful song):

The previous successful playback of music did no such ‘auto-select’. Looks to me like something got confused about what the content type is!
