The main takeaway for me about Taylor Swift is that she learned a very hard lesson early on in the music biz about record deals. I believe it was FZ who called it the international hum job.
She's really taken the lesson to heart, too. To the point that she's doing a Sinatra re-recording her own stuff to a label she controls. I think FS and FZ are very happy somewhere as they watch her laugh all the way to the bank.
I am, too. Too many artists of all stripes get badly ripped off because they aren't contract lawyers. If even one little kid follows her example to avoid her teenage naiveté, that's a win for society at large and artists in particular.
