@Ratttz We've never liked when a game has music just for the menu; since it's the same throughout the entire game, and you go into the menu a lot when it's an RPG, it gets grating after a while. Just keeping the area background music is preferable, though it's good when they reduce the volume a bit.
Overworld music falls into this same trap sometimes, which is why it's nice when games change overworld music partway through; the Tales series tends to do this for instance.
