I like that in this, like most other performances of this song, she doesn't try to go up the oatcve on the refrain (like the single version) that's clearly out of her comfortable range. Not everyone has to have a dogwhistle Mariah Carey range (always found her overrated) to be successful. Stay within your range and sing your heart out, your voice and fans will both thank you. Nat King Cole, for one, never much strayed out of a few oatcves, and he has one of the most beautiful voices ever.
