This is the fun bit of any art, and here on Lemmy where we have a lot of analytical people it's hard to define. Art isn't inherently good or bad, and it's a deeply personal thing. People here love to say Taylor isn't good, her music is boring, etc. That's their own personal view though.
Hwre we have someone who was inspired by Taylors music and decided to make something of their own.
Its why I don't understand tearing down people for what art they enjoy. Art begets art. The very cool thing is that if you don't like it you can go enjoy other art. If you do though, you can make something fun yourself.
