Marc is jealous of Mariah. You're right though Rihanna is a studio vocalist. You are in no place to talk about real singers when you STAN for one that is least known for actual singing. Sit TF down.. Adele has three incredible albums. She has a huge fan base! She is incredibly gifted! Outside of her sales her albums are amazing! Aretha is a hater. All of those women are way more successful than her. And the most influential female vocalists are Mariah/Whitney.. Aretha is very callous & rude!
