Songfacts®:

• The lead single of Christina Aguilera's Liberation album is this hip-hop inspired, sexually charged anthem featuring 2 Chainz and Ty Dolla $ign. Christina and Ty handle the chorus, during which the pop songstress urges the hip-hop artist to "accelerate," or go to faster, while having sex. 2 Chainz delivers a signature verse just after halfway through the track.
• Although Aguilera has previously collaborated with a string of rappers, including Lil' Kim, Mya, Diddy, Pitbull, Missy Elliott and Redman, she described Liberation to Billboard as being her most hip-hop-inspired work yet.
  
  "To me, there's nothing like an amazing hip-hop beat," she said. "At the end of the day, I am a soul singer. When you strip back the words 'pop star' and the many things that I've done, singing soulfully is where my core, my root and my heart really is. And as you can see, it's what I'm inspired by."
• The booming club song was co-produced by Kanye West (who's also credited as a lyricist and composer). Aguilera and West linked up for this track around the time Kanye was gearing up to release The Life of Pablo, after first meeting at producer Rick Rubin's Shangri La studio in Malibu, California in late 2015.
  
  "I've always been a huge fan of Kanye," Aguilera told Billboard. "Outside of, you know, his controversial aspects, I just think he's a great artist and musicmaker and beatmaker. The artists that he chooses to pluck from different walks of life are so interesting."
• The music video was directed by Zoey Grossman, who also photographed Aguilera's barefaced March 2018 Paper Magazine cover. The singer gets covered in glycerine during the clip. She told Entertainment Weekly laughing: "It's so sugary! It's disgusting. I kept my mouth shut the entire time. It's not that fun but it feels really cool on your body."
• In the United States, the song only had minor success, peaking at #124, but "Accelerate" did become Aguilera's 10th #1 song on the US Billboard Dance Club Songs chart.
