“21st Century Girls” (unofficial title) is an original song by Olivia Rodrigo. She posted a clip of the song to her Instagram on April 26, 2020 with the caption: “today I took the classic Instagram dive, comparing myself to girls incessantly and wishing I had what they looked like they had. it’s so silly how we/i define ourselves by the most arbitrary things and idolize ppl who are humans just like us. anyway, i wrote this song today about the tendency I have to go down this self sabotaging hole and now I’m posting it on Instagram because I love irony. if ur reading this pls know that ur value is so inherent. it’s not something that could ever be defined by something as contrived and manipulative as social media. you are so loved!”
