Final Fantasy XI had awesome airship music, but I think the reason it was awesome was because it was purposely cliché to classic Final Fantasy airship themes. I could imagine it being on an NES or SNES Final Fantasy game, so I think it was my favorite, although... It's kind of weird to think it's my favorite for the reason that it's reminiscient of the older ones.... I dunno, maybe the concept just makes it that much cooler. I say FFXI.
