Don't get me wrong, the mount is very unique and a great reward for a great dungeon, but I would be lying if I said I didn't feel a bit disappointed that it just plays the stock flying mount theme.
Reminded me of whenever I finally got Fenrir, and it didn't play "The Warrens".

Alternatives to "Turmoil" could be "Gates of Paradise -The Garden of Ru'Hmet" which plays inside the Baldesion Arsenal, or "Onslaught" which plays during the other boss fights.
Even the Eureka theme would be a good alternative, although if you've beaten Proto-Ozma you've probably had your fill of that song.
