The difference with Taylor Swift is that she actually writes and sings and plays some guitar.
Joni Mitchell, to the best of my knowledge was the only other female entertainer to do all three and see near the success of TS.
I am not a Swifty, but I will admit she is quiet impressive.
FYI, two fifty something year old dudes in my office are in the Taylor Swift Fan Club. They were also in the Hannah Montana Fan Club. They each bought tickets to last years Era Tour. Then listed them on Stub Hub and sold them for around $500 profit for each one within 24 hours.
You’re comparing Taylor Swift to Joni Mitchell? LOL!
Actually, that is NOT true.
Rick Beato (YouTube Channel) exposed her as a fake who has other songwriters write her simplistic songs and she takes credit.
Additionally, Joni Mitchell's songs has quite complex chords and she recruited top jazz musicians to play her music in the studio recordings and live concerts.
Further, Joni's lyric's are waaaay beyond TS in substance & complexity.
Only a low IQ idiot would even mention TS in the same sentence as Joni Mitchell
