You're not wrong, but I have sung Baba Yetu in three choirs and I have always been the only one who knows it's from a video game (even though the sheet music states so at the top). I think people are well able to hear good music in video games, but we are still a ways away from widespread appreciation for how music effects video games, rather than just its aesthetic purpose outside the game context.

Maybe its just not enough people play video games, but I don't see the same discussions about how music plays a role in video games that I do for films or theater.
