Ah, I think that might be an unnamed rip. Unfortunately, not all of the anime's tracks have been officially released. I'm familiar with that Youtube channel; they rip tracks from anime that haven't been officially released and clean them up. I'll take a peek at the OST later just in case, but I feel like it's one of those unofficial releases without a name.
