Weird that this got downvoted. In response to "Is ${artist} that good?", I link to an objective list of awards and accolades showing that ${artist} is very good at their job. Compare Swift's success against the Beatles, Dolly Parton [1,2] or anybody else, and it's a very strong showing. If you don't like the art, that's a completely different matter. But in the sense of whether Swift is good in the way that matters here, the answer is clearly, "Yes."
