Vanity Fair:

Taylor Swift’s recent missive to Apple—the one that caused the tech behemoth to reverse course, once again demonstrating her world-beating pop power—came after some late-night soul searching, the singer tells Vanity Fair writer Josh Duboff, in the magazine’s September cover story.

“I wrote the letter at around four A.M.,” Swift says. “The contracts had just gone out to my friends, and one of them sent me a screenshot of one of them. I read the term ‘zero percent compensation to rights holders.’ Sometimes I’ll wake up in the middle of the night and I’ll write a song and I can’t sleep until I finish it, and it was like that with the letter.”

As whiny as I find her music, this story shows a very self-aware young woman who knows what she wants.
