Don't let the spiritual-rebirth title of Xtina's fifth LP fool you. Christina Aguilera has only one religious affiliation – the cult of the voice. And she has a great diva theme to rap her pipes around: surviving a divorce. "Spin around in circles on my middle, middle finger," she sings on "Circles." Producers like Shellback and Max Martin give her top-line tracks to body-slam, but, sadly, her bombastic breakup ballad with Blake Shelton, "Just a Fool," sounds more like a battle round on The Voice than a friendly duet. It's just one telling moment where this vitriol-tsunami of a record misses a chance to connect Aguilera's music with her warm, empathetic TV presence.

“Youth Knows No Pain”

“Like on 'Youth Knows No Pain' — we are the ones that should demonstrate, because we can take it,” Likke Li said. “We can pierce ourselves, take Ecstasy, dance all night and still go to work at our McDonald's jobs.” Despite the hedonistic sentiment in the song, the Swedish singer also admitted in hindsight her youth had repercussions. “I remember when I was 18-19 and feeling that I know it all,” Li said. “I always feel that I know it all. But that song is about realizing you don’t, and reflecting, ‘Boy, if I only knew what would follow.’”
