Unwritten was released in 2004 as the title track of Natasha Bedingfield's debut album and became one of the defining feel-good pop songs of the mid-2000s. Its use as the theme for MTV's The Hills kept the chorus in pop culture for years, and the song found a second life after its joyful singalong moment in the 2023 film Anyone But You. Short clips of the rain lyric now circulate on TikTok and Reels, where the line works as shorthand for freedom, healing and starting over.
