Fuck. YEAH!
As far as completion, that would be something Sink would know, as he played through the game. If it is complete, then I am literally one track away from finishing the soundtrack, sans some alt tracks I want to record (haven't recorded the third track yet, but I'm at a part that plays the song so I could do it whenever I feel like it).
EDIT: Oh yeah, I noticed it's missing the first battle theme (which is really catchy) and the song that plays during the meteor shower cutscene early in the game. I don't remember off-hand if there's anything else missing.
