I'm not saying she will not, but she hasn't "surpassed" anyone yet, it could be another BTD just the same way it could be another Revival in pure sales.
In the general sense, she has beaten Selena and Demi but I see your point.
Nah. Katy's best vocals are good bit better than Taylor's.
Taylor has a practically vibrato-less, light, and fairly weak voice. She has good tone but as for vocal capability she's without a doubt dead last.
Needless to say neither are anything special but at least Katy has some resonance and weight to her voice.
I mean Taylor's a soprano and the strongest part of her voice is her lower register, that says enough.
true hence katy is a slightly more talented vocalist however her skill is lower than Taylor's making her good performances far and few between
It's not to late to scalp Into You for Side To Side, Into You can be re-released as the 3rd single after the VMAs with visual two. Anything to save this era
