Mariahs whistle register and low notes have actually improved over the years. The raspiness in her mid range has disappeared due to pregnancy. She can still belt properly upto F#5 given proper conditions. Her voice isnt as strong as strong before thats true ciz she had nodules and she overworked it.. But what the girl did was just hiyting some some whistle notes, and that doesnt make her a new mariah carey. Sam is an idiot
