Glad to hear about a toggle. Can they maybe add an option to have it play for a bit but auto-fade after a single loop of the song? That way I can still hear it when i want to, but on longer rides I'll have the chance to hear the zone music as well. I'd also like the ability to switch, or randomize, which chocobo music I hear--I got my personal chocobo the day they were available so I've barely heard the rental choco music at all.

I also think Rane's idea is a decent one, to have certain zones totally override the mount music for atmospheric reasons. It'll give kind of a "Not even your giant chicken can't protect you now" vibe =P.
