I'd take the worst SIO performance over any Arihanna performance any day. The way she sings through her nose in one big breath with no articulation and it just sounds like all one word. Omg wtf.
tbh Taylors only victim (not counting the men that have suffered greatly under her) has been Carrie Underweeds career. But Taylor could take Katy's place easily in the pop scene, she is younger and more talented and even though shake it off is tragic it's still nowhere near Roar which was brainless antimatter.
