I can understand not wanting this suggestion, like you said there are legit concerns about overcrowding and the like, but you're on shaky ground if you base your argument on it not fitting the Final Fantasy archetype. Music is all over Final Fantasy, its in its blood. As a video game series it has some of the best music in the industry, its no wonder that music spills over to the lore of their respective universes and not just in the form of music based combat classes.
