Sia Sings Britney's "Perfume"

Sia gave an interview to ABC’s Nightline this week, sort of. She faced away from the camera the entire time in an effort to remain anonymous. They discuss her lengthy body of work, including DJ Guetta, Rihanna and Britney Spears.

During the segment, Sia sang Britney’s “Perfume,” the first time it’s been sung live since ever, and it’s magical. In fact, she wasn’t sure she even remembered the words, noting they make a song in 40 minutes and send it off and never hear about it again.

“I just lift these concepts off like crap television,” Sia says. “And then it’s like so fun, and I apply them to music… There’s a story. It makes us feel good, or it makes us feel sad.”
