The fact that Into You lost 3.370 audience.

And some of you didn't believe me when I said radio would start dropping Into You like a rock as soon as Side To Side got sent for adds. As I've said, radio only makes exceptions for certain artists like Taylor (but I'm sure she does a sh*tload of payola, seeing as Style and Wildest Dreams are still in the top 100 of radio - higher than Dangerous Woman).
