"Baby" Is The Fourth Single From Charli XCX's Fifth Studio Album Crash. The Track Is An '80s-Inspired Post-Disco Dance-Pop And Funk-Pop Track With New Jack Swing Elements. It Has Received Positive Reviews For Its Catchiness And Sultry Production. Charli Explained In An Interview With Apple Music That "obviously So Much Has Changed And This Song It Was Kind Of The Foundation Of The Vibe Of The Album. It's Probably The Most Sexy Song I've Ever Made. It's About Sex And Sexuality And Having Good Sex And Just Feeling Yourself Essentially. I Know That That's The Tone. I Knew That That Was The Tone I Wanted To Carry Across For The Entire Record. This Kind Of Hyper-Sexualized Feminine Power Zone Was Where I Was Feeling Myself Going And "Baby" Was The Genesis Of This".
