Okay TGJ this is no big feat, a few clicks on youtube will show you that this song can be sung by many and very well. Also, i was about to say what @random wrote. Leona was the new Mariah and she turned out to basically be a one hit wonder even with all the big guns behind her. Whilst Ariana can sing she needs to be a lot more diverse with here range and techniques and drop a lot of the Mariahisms that she currently has. Please dont overexpose like you do with Elijah Blake, Rihanna, Beyonce and luke James
