Depends on what kind of pop you're into. If you liked 90s Mariah (yeah, I went there, just like everyone else...it's unavoidable) then it's perfect. If you like trap snares (lol) it's perfect. If you know what vaporwave is at all, it's pretty good too.
Whether Beyonce has hit after hit or not, she definitely has star power - none can deny that. Taylor is definitely not a legend, and Britney isn't either. One is viewed as a country sellout/joke while the other is still deemed as mentally incompetent by the courts.
Being a legend is all about a fame, not about star power or vocals, tho.
