Many games include an option to mute the game when you're alt-tabbed to something else. I'd love to see this in game as well - bonus points if the program icon lights up when queue finishes to let you know there's a game, even on mute.

I would LOVE this option. I want to leave the music on but when I'm queued between matches it stops me from watching youtube or w/e else because of the audio "pollution" of cars driving by and such
