My choice would be Symphony of the Night, that game just kicks ass, enough said. Well my fave song from that game would be The Tragic Prince, that song just pumps me up:naughty: .
SotN: Either "Prologue" or "Dracula’s Castle"
LoI: "Lament of Innocence (Leon’s Theme)"
CoD: "Abandoned Castle (The Curse of Darkness)"
All 3 of those get stuck in my head quite easily.
I haven’t played all the Castlevania, but from those I played, I prefer the Symphony of the Night themes, specially the 03 (Dance of Illusions ?) and 05 (Prayer?) tracks. Not sure of the names. The 03 features eerie ans smooting/gothic rhythm with a female voice while the second has harpsichord… I love that instrument !
I knew SotN OST before actually play the game, and still love it.
My favourite is The Gears Go Awry by Yuzo Koshiro.
Uh… Yeah. My favorite soundtrack from the Castlevania games is obviously Super Castlevania IV, because of one track…
…and that track is "Theme of Simon Belmont". Come on, you guys aren’t retro enough.
