I'm curious though, why Kirin? It's a horse, and horses are not exactly associated with the FF series, so adding the FF theme as Kirin's mount music would not exactly fit IMO (and the 1.0 version to boot - in 1.0 it was actually the character creation theme). I'm sure another track could be found that would fit it, but to me, Final Fantasy does not. But that's just my opinion so carry on!

While we're on the subject of mount themes though, maybe changing the Legacy Chocobo theme to Bo Down (the theme used for rental chocobos and Chocoporters) - I just prefer this to Eorzea de Chocobo and feel it would be a closer match to the Legacy Chocobo's lore, being a 1.0 character's 'original' mount and all.
