They're pretty solid vocals, caught me off guard at first, but that's probably because they are a fair bit different from Yourself's vocals, but I got used to them quick.
Shadow Meggy's vocals for the song and the possession segment were really good! The lyrical segment did not really work though (which part of it is the ai's fault, it just couldn't hit the notes and it made it sound off.) Not hate to your cover btw, it's really good1
