May be a longshot, but I mentioned this producer on the VVN server and now I'm trying to actually find them and can't. I've only heard two of their songs (one was a preview on twitter, the other was on Nico) and they were really similar, so I think it's safe to say that their style is just like this. I'm gonna talk about just the Nico song, though the twitter preview was a screen recording of their DAW, I believe.
I can't remember the song's genre; if I had to guess, it'd be rock? I don't remember the video either, I think it was plain white with black text -- don't remember the illustration, if there even was one.
Here's the part that may actually narrow them down: Miku sang super high. Like, really, really high -- way higher than most high Miku usages, wouldn't be surprised if she hit the top of the editor. I can't remember if she was low gen or not but it didn't matter; the chorus was... certainly something, but all the Nico comments were nothing but praise. I don't think they're a super popular producer, but they may have moderate popularity? The song when I heard it was brand new, so I don't know how many views it would have by now.
The year is either 2018 or 2019 -- maybe 2017 at the absolute earliest, but I think it's probably 2018. Somewhere in that range orz. I don't remember anything about the title but I think it was a long one? But take that with a grain of salt
Oh, I think Hazuki no Yume may have translated this song at one point too, but I'm not 100% sure. I don't remember anything about the lyrics, though.
If anyone at all knows who I may be talking about. please tell me this producer's name or link any of their songs I want to experience it again
