Image 1 and Image 2 (Sources: https://www.youtube.com/watch?v=XvclwsR ... .be&t=1m7s and https://auctions.c.yimg.jp/images.aucti ... s28489.jpg)These are the only official sources so far (i.e. the rar you have posted). So, you are obliged to stick to it, no matter how the other unofficial references show.
Amazon and all the other third party retail sites (also the mp3 file, I supposed you downloaded them online? Fields are not even in Japanese?) are not official, so they have zero value on justifying usage of CV in the Artist. Shitty or not shitty is not the matter to judge the accuracy of metadata, correctness is the officality in this game, not based on the usual / common practice. What the official says has the highest priority.
You also mentioned design mistake, how can you prove it? I mean, there are also some other songs which use small letters instead of big ones in their artists, like this one or this one. There is basically no way to verify and what you said is thus pretty much worthless.
Let me repeat again, the cover is definitely the only credible and official reference showing the current artist, all your justifications and what you linked are unfortunately untenable because none of them falls into the category of official references.
Frankly speaking, I am stunned that you consider yourself winning (on such pretty things lol) provided that you do not even have a thorough view on the ranking criteria and how metadata works in this game. I would not say "I win." but I hope you grab at least some very basic knowledge on this matter.
@Asuka_-: send me the forum PM they sent you, let's see what I can do.
