every voice you hear from her God-ish cover is her hahaha, that's just how amazing her range is and how she can just easily shift her voice on a different kind of expressions/emotions! with that said, i highly recommend ado's Eien no Akuruhi 💕 it's more of an emotional song and the way she sings it always touches my heart 😭
Hollowness by minami is one of my favourite songs ever, pls listen to it even if you dont do a video on it For ado i would recommend crime and punishment
Ado always has such amazing music! Still hoping you’ll consider Gegege no Kitaro AMV (A.M.D.K.J.). A.M.D.K.J is a banger from SCANDAL and this AMV shows off Gegege no Kitaro (2018)‘s great animation. Truly believe you’ll enjoy it. I’ll be happy even if it has to wait until you do ending songs, and not sure if you were planning to already. If you already were apologies in advance.
I'd recommend checking out Yoru No Pierrot by Ado, the Teddyloid remix version slaps extra hard but both versions are great. Minami has a great catalog of songs too, Hollowness is high on the list of ones to check out though.
Next song: Odo Aaaaaand just a shout: Have you ever heard of hololive? It is a group of vtubers and believe me and there are great musical talents there. There is a song called Off with their heads by Calliope Mori that is simply perfect the way to answer her haters XD
Minami's "hollowness" is her best song in my opinion, even though she's more well known for the domestic girlfriend op. But you won't go wrong with any of her songs anyway.
