There are tracks missing. You can tell if you watch any gameplay video.
This OST has been on the site as of the upload date.
It wasn't there before, I know that for a fact - so it seems the other people that had been eyeing the Phantom Blood OST (it was uploaded on the same date) like I was, achieved their goals.
The same person probably uploaded it.
I'm only saying this cuz I was on the lookout for when the uploader was gonna release it (took him long enough, but I'm thankful), so it's cool to see both here even if it's incomplete.
