[Suggestion about metadata]
I'm going to shortly explain 3 minor changes I would make about metadata's song, all 3 aren't too relevant and can be skipped but I thought they could be positive to add them so there they go.
According to this website "https://remywiki.com/Camellia_"Remixes"_Summary_%26_VIPs_02" (tried to search the most confident source, I might be wrong) I think "Camellia feat. Nanahira" fits more than only "Camellia" on Artist.
You can also add "Dempa Machinegun Psystyle" on Tags section as the beatmap name has only the inicials because of beatmap name length limit. Also I would Consider adding "Voltage Ignition 2" on tags as the non-remix song is from that album.
