I notice the iHeart performance is very polarizing. You could say it's her best or worst performance.
Some people say she sounded like she was congested, nasally, cracking voice, and had a cold.
Some say she was beyond on point, her voice and piano skills were beyond that, and she SLAYED.
And it's her best performance because it is not ignored, but actually elicits a response of love or heart from people like a true star.
