Seriously. The rental chocobo theme (in my opinion of course) sounds so much better than the personal chocobo theme. Although its got a western cowboy feel to it, it still feels closer to an original theme you'd hear for a main series Final Fantasy game...and is much more catchy than the personal theme to boot.

It would be great if players were somehow given a choice as to what chocobo theme you hear when you jump on your personal chocobo, even if it has to be some sort of quest for a key item.
