For those who do not know who Ado is, she's a utaite singer from Japan (utaite is someone who covers songs, mostly vocaloid songs, and usually never shows their face)(there's alot more info about utaite, i recommend searching on web because i shortened it) She's just 20 and she has a lot of hit songs, she debuted with "ussewa" when she was 18 and it was a megahit in Japan. Highly recommend listening to her, her voice is INSANE
