Pop superstar Christina Aguilera released her new song "Twice" on May 10. She gets back into ballad mode following comeback track "Accelerate."

"Twice" is one of the songs on Aguilera's upcoming album, Liberation. She previewed her return last week with "Accelerate" featuring Ty Dolla $ign and 2 Chainz. The electro-funk track was a girl power anthem with plenty of sass and trap music elements minus the melisma Xtina is known for. With "Twice," she uses her vocal growl once again to reflect on life and love thus far. "Am I in heaven? / Am I in hell?" Aguilera asks herself before belting, "I can barely find the proof to save myself." It's a hauntingly beautiful reminder that she can still bring on the heartbreak like the best of them. There's no thinking twice about it.

"Twice" is now available on iTunes and Apple Music. Aguilera's Liberation album will be released on June 15. On May 20, she will debut "Fall in Line" featuring Demi Lovato live at the Billboard Music Awards.
