Does anyone know of a way to stream music to your console while a game is playing in full screen? Last night the best I could do was snap the media player and then stream music via Plex onto that. But if I ever put my game on full screen then the music stopped. All I know is that I had more fun playing Titanfall with Rush playing through my headset at the same time than I have in a while and I'd prefer to keep doing that without having the game screen get smaller.
No. Unfortunately that was a possible on the 360 but the Xbox One can't do it without the app being snapped. Hopefully when they upgrade to a Windows 10 style interface they will fix that problem.
