It's nice in some games, but in most games I'd rather listen to the game's own soundtrack anyway, as it usually fits better. And in multiplayer, I have much better use for my ears than listening to music, such as listening for my opponents 
In the end, I think it's fine the way it is. It's an artistic choice for some and a ressource choice for others, if you want it in a game, tell the developers and maybe you will get it.
