She is dramatically overrated. It is an interesting phenomena when it happens.
Why large masses of people will like anything a performer does without any ability to critique.
In the 1960s, Paul McCartney could have recorded a series of farts and their die hard fans would have loved it. Taylor Swift is the same.
I have loved music all my life, almost any genre.
I rate Taylor Swift as such:
Scale of 1 - 10
As a Performer - 10
As a lyricist - 7
As a song writer - 3 (Why so low? Well the songs are not all that good, very replicated and although she is credited as lead songwriter in every song - she virtually never writes the music without working with song writers.
As a singer - 5 (Let's face it, she is not that great of a singer. Constant use of background singers, uses auto-tuner when recording, Swifties will defend her in this - but they would defend her eating poop.
Overall - 7, her brand performance and stage presence is really what makes this number as high as it is.
Without the performer talent and looks - 5
There are a long line of female artists ahead of her in talent. But Taylor has the fan base regardless,
