• This emotional piano-driven power ballad finds Christina asking forgiveness from a lover that she's hurt as she pleads for a second chance. Aguilera said at an album preview event this song reminds her of one of previous powerful ballads, "Beautiful." "It's almost reminiscent to me of the quality of song, to me, that's so vulnerable and so empowering that 'Beautiful' is, but in a relationship way," Aguilera explained. "It's about being OK with saying you're sorry and the fact that you might have regrets, but it's about finding closure and making peace with yourself and the situation. The song is sort of the heart of the record."
• Aguilera penned the vulnerable ballad with English Pop songwriter Chris Braide and Australian singer-songwriter Sia Furler, who previously worked with the songstress on some of her tracks for Bionic and the Burlesque Soundtrack. Regarding working with Sia, Aguilera told Billboard: "It's inspiring to be around real creative energy."
  
  Sia originally wrote the song for English singer Leona Lewis.
