If she has been struggling for years already imagine what will happen with Ariana Grande and any other upcoming girl who tries to emulate Mariah Carey in some way. Cause Leona was so much bigger than Ariana during her debut album, much bigger. She was invited to sing teh song for Avatar (in a bad attempt at recreating a My Heart Will Go On type of situation, didn´t go anywhere, but she was the chosen one), she actually had a big #1 single in the USA and worldwise, and she sold some damn good millions of real album copies. I remember seeing ehr performing at the Olympic Games in China. Ariana has only had a few forgettable and generic attempts at singles that I think have not even been #1 and that´s it.
