Mariah has a bad day...she's rich. She's legendary. It doesn't manner. Any other artist has a bad day...she's tired. She's late. She can't sing. She should retire etc. how's that so? it's clear to see there's an issue of some sort thats negatively effecting her vocal ability. Maybe time, age, stress, drinking who knows. Idk if she a smoker but let's not act like she doesn't start drinking wine at 9 am. lol it's part of her legendary persona...a cocktail, perfect lighting and a teddy. I'm low hey here for it lol No shade...all entertaining from my perspective lol
