okay here is my thoughts on every version on this video.
FFII, the original, nuff said
FFIII, alittle better than the original.
FFIV, like the ocarina sounds! (anything with an Ocarina i fall inlove with)
FFV, this one is funny , considering Chocobo is a main character in the game.
FFVI , as much as i liked FFVI , this one is noisy and had rick astley's sound to it (as why its named Techno De chocobo).
FFVII , This one is awesome, its a very very good change from the crappy world theme.
FFVIII , this one wasn't noisy when i played it , but it was different.
FFIX, this is my favourite
FFX , this is the most one i heard, they changed it some.
FFXI, best MMO "Mount" music ever.
FFXII , ??? i seriously don't remember this one, i remember this http://www.youtube.com/watch?v=nlyV0IPjwq0
FFXIII , it sounds like a competition maybe a chocobo race?
