Other jealous and insecure fans thumping their chests about "vocals" (even though their faves miss EVERY SINGLE NOTE when sung in a completely raw setting), meanwhile Chaewon proves to you exactly what i've been saying. Kpop has never been about vocals and never will be.
THIS IS KPOP NOT BROADWAY OR OPERA.
While your faves sound like dying cats screaming in the middle of the night trying to belt out random E5 notes in the middle of a freakin boyband song . Chaewon CAPTIVATES you with a soft spoken, lyrical vocal. She doesnt have a Mariah voice obviously and she is straining to hit some of the notes in the climax, yet she captures EMOTION and conveys that to the listener. This is why this cover is so popular. The straining itself is what helps make this song SO INTOXICATING.
Music isnt about sterile vocal techniques and pitch matching. Music is about STORYTELLING, engaging the audience, getting them to listen to you, to dance with you, or to cry with you.
