So limited and deceptive knowledge of a person--esp in the sense of not knowing if they're FiSe or SiFe, which she is really neither. I'm curious, what do you consider to be N? How special is it to you...
Examples of NF lyricists: Tori Amos, Nick Cave.
NFs typically have better grasp of metaphor and don't pass off simply writing the way that people talk as "art." It's not about how creative a person is...SPs are frequently very creative...but this tends to show in style of creativity and methods employed. She doesn't strike me as someone who writes concept albums, or approaches her song writing in an abstract manner. I don't see her use of theory or symbolism
anywhere. She doesn't even seem to have a higher political or social purpose. NOTHING.
Despite your criticism, I don't see you making any solid argument at all for any functions. At least I gave reasoning and evidence. If you want to imagine that she's an N just because you like her, or because she happened to make a rather cliche reference to Romeo and Juliet in one of her songs, that's a bit preposterous.
It's not even that I don't think that ISFP can be creative, many of my favorite musicians or visual artists are SP...this isn't a criticism of ISFPs, in general. I just think Taylor Swift happens to be an S, and not a particularly original or creative one....which as strikes me as heavily ISFJ, frankly.
She's a very pretty girl and she seems very sweet. She is capable of producing mainstream country hits. That does not make her an N. If anything, she strikes me as being just another manufactured pop sensation.
