Posts like this take Taylor completely out of context
She's said time and time again that she doesn't need more money, and even if music didn't sell she's fortunate enough to make it in other areas like touring and endorsements. She's doing this for the integrity of the art of music itself, and for all of the people who work on an album who don't get paid in any other area than sales.
I get Miley's stance but she should think about the people who worked on her album who need those sales to make money.
