Not really, this is the official name (in terms of translation), you can’t just go with the fan term names if the official names are out, plus the views would probably be about the same since at that time, it’s just “official version” is more appealing to people since it contains the official release of the theme people like, probably better than to give it a fan name (as at the time, people don’t really care about that since there’s many people that uploaded that ost using that name). Edit: I think I had a stroke here, to explain it better, adding the word “official” and giving it the official title is more appealing since there are some people out there that wanted an official version and it just lets other know that they finally get to listen the whole entire thing without relying on other people’s attempts of ripping the ost (the ones where you still here background sound effects or voices, or are apparent).
