Its so weird how after only 1 underperforming single people on atrl are already talking about Ariana being "replaced". Like Ariana isn't over and she can very well bounce back from this so why ask this question? Lets wait and see if Moonlight outsells Revival (it most likely will). Just cause Selena is hot at the moment doesn't mean she replaced anyone. These threads are so redundant.
Some of you are so damn stupid with this "has x replaced y" shizz. Purpose has almost 350m views on VEVO...her power is still there. Just because Selena gained two moderate hits last year does not mean she replaced anyone. Her and Ariana do not have have the same image, or release the same kind of music...what exactly did she replace?
Please stop these threads. How could anybody know? Yes, of course Selena is the biggest out of Miley, Demi, Ariana & Selena AT THE MOMENT. But Ariana's huge era was only 1 year ago. Her comeback could be huge.
