This is Britney's last truly great single for me (her last million seller in the States I believe, although "Make Me" may be close), and it sits firmly in my all time Britney top five. How do we feel about it six years on? Also, the video elevates it that much more. She gave so much weird nervous energy off in 2011-2013 but for some reason she completely delivered here. There are so many good shots of her.
