Yo, was there ever an OST release for this series? The music, in particular the opening theme by MIO (who goes by "MIQ" now, I guess) is incredible in that 80's way.

I found this on a google search, looks like there was 3 OST's and a vocal album called Palladium...  There's a CD single for Aura Battler Dunbine still available thru CD Japan too.
