Youtube is just a tool, that's why in the descriptions (not only for these but for everything music related) you'll always find the "provided to Youtube by...", it is always mandatory to offer at least the name of the recording label, in these cases they just mention "Nippon", as Ghost said, there is no way that the real Nippon Columbia is responsible given the messy nature these uploads always seem to have, also, not only on Youtube, but also on other platforms (
Spotify for example)
I think the artist name of the content owner in my main post was the biggest red alert so far, I also checked recently a copyright claim in Solid State Scouter and there is this Frankenstein:

(If you google Interstreet Recordings and Audio Salad you'll find the same thing as [Merlin] Revelator)
Honestly I actually thought there could be a chance that the person or people behind these copyright claims and uploads could actually be from Japan, since in the description of a few uploads the date is not the day the uploads were made, but the day after, and the possibility that they are using a bot just made me think more about it.
But now, lol, George??
I simply wouldn't want to imagine my life without Dragon Ball, thank you Akira Toriyama (1955-2024), you are now immortal ~☆
