Christina Aguilera admits that her last album, 2010's Bionic, didn't connect with her fans. "It had a lot of amazing sounds and a futuristic twist to it," she says. "But if you weren't a music person, it was just going to go over your head. A lot of the collaborations were with people that were either very underground or weren't necessarily from the pop world. I really think it was far ahead of its time and it'll be fully appreciated in the years to come."
