They don't need a backing track because they aren't doing really hard dances for this song. Since they're mostly standing they can sing at their highest potential since it's harder to sing when dancing.
Riwsty Dhaka Fofana I know. I was shook that he was singing the whole song with the freaking vibrato which is really hard 👏🏿 I don’t know how you read my comment.
1:08 Chanyeol sounds so great,I think he has an unique voice,deep,strong,husky voice,I thik he is a great vocalist but he is so underrated as a singer.
