• This raucous cut finds Miley Cyrus looking to make a connection without going too deep.
  
  Love me now, but not tomorrow
  Fill me up, but leave me hollow
  Pull me in, but don't you get too close
• "Plastic Hearts" is the title track of Cyrus' seventh studio album, a record where she frequently touches on how it's hard for her to commit fully to a relationship. "Angels Like You," for instance, finds her apologizing to her romantic interest before walking out on them.
• When asked during the first episode of Amazon Music Holiday Plays about the meaning behind "Plastic Heart," Miley said her homeless charity Happy Hippie inspired the song. The "Midnight Sky" singer explained she wrote the tune following the annual Christmas holiday party Happy Hippie throws for homeless youth in Los Angeles.
  
  "Right down the street from where we are right now, there is more homelessness than anywhere else in the country - this is kind of the nucleus of homelessness," she said. "So really knowing that I live in this extravagant world and so many homeless kids are on the street it just never really felt right and so this song was dedicated to that community that is so important to me."
• Miley Cyrus wrote the song with Ryan Tedder, Ali Tamposi, Andrew Watt and Louis Bell. The same quintet also penned "Angels Like You."
• The song's intro references The Rolling Stones' "Sympathy For The Devil," with Stonesy percussion performed by Red Hot Chili Peppers drummer Chad Smith.
• The song's demo version, titled "California Dreamin'," was leaked online. It is also known as "Keep Me Up."
• Miley Cyrus sung the song on the May 8, 2021 episode of Saturday Night Live, hosted by Elon Musk. She also teamed up with The Kid Laroi to perform his remix of "Without You."
