The time she spent with producer Danger Mouse was an experience she'd like to duplicate. "He's like a sponge, he just soaks everything up all around him," she said. "I went to his studio in L.A. When I was there--I just love him. Next time I'll probably spend a month to six weeks just working with him."

If she'd had her way, the first single from 25 would have been "Send My Love (To Your New Lover)," but ultimately that "more poppy" song was less representative of the album as whole.
