You yourself know you're lying so just stop...this narrative is getting tired....even powerhouse vocalists in the west have times where their voices crack even without moving....while these girls have some of the most hardcore choreos and they have to sing at the same time so obviously they won't sound perfect all the time but you go and pick only the times where they miss and make them viral and obviously ignore all the thousand times they do well....get a life, that's all I'm gonna say
