What PQs/bosses would be like if I designed them.

I didn't really understand the musical motifs you were referring to, considering I've never heard those BGMs you were referring to; but I just tried to imagine the concept at least.

k, I've got the links. These are the themes I mentioned when I was trying to state what the themes' tones would sound like. These wouldn't be the actual soundtracks, just ideas of what I'd pick as their general moods.

Zakum underworld PQ:
Magus' Castle (CT) (starts around 0:30)
Book of Sealing (FF5)

Goliath and Qellyn battles:
Masamune battle (CT)
Alishar theme


Mount Fuji PQ:
Ice Palace (SoM)
Snow levels (DKC)

Lance:
Edguy (this may sound familiar to some; the best Crusader video ever made was set to it)
Trans-Siberian Orchestra (I'm actually going to see them at Nassau Coliseum 3 days before my 27th birthday, next month)


Ludi dungeon PQ:
Phantom Train (FF6)
Ghost Ship (LoD)
Legend of Legaia

Phantasmal Amathar:

Magus' Theme (CT)
Ghaleon's Theme (Lunar 2)


Miliae PQ:
Vane from Lunar
Itory from Illusion of Gaia
Legend of Legaia

Saradin:
Ogre Battle underworld boss
Mordor theme (Starts around 1:10)


I'm honestly not quite sure why I didn't choose themes for the bosses. I figure each dragon would have its own theme or maybe one common theme, maybe sharing them with the PQs' bosses. Amathar himself is a villain I designed for a first edition AD&D campaign about 4 years ago. I've always pictured his theme as something of a cross between Michael Angelo Batio and the London Symphony Orchestra.
