>>680531np, usually those kinds of little tracks you can't find, probably like mine here as well
>>679499 are either such simple chord progressions and basic melodies/rhythms/whatever that they can't really be licensed as a company's own work.
it could be something like that. idk. maybe it's just that rare, or like you say an unreleased. i'll keep looking though so long as the thread is still up.
maybe there's a list of people who worked on the soundtrack for the series that you can find and get in touch with. that'd be pretty cool dude.
