She'd better show some respect for one of the greatest vocalists of all time, the one that outsold her many times over, the one that left much more impact her than she will ever leave, the one she can only "suck so bad at Mariah Carey-eoking" and the one that has Grammys.
I know Mariah is not the biggest star in the world atm, but "good for a throwback" is offensive for someone who's influenced countless artist of Katy's generation. Bye.
