All Too Well

"All Too Well" is a song by the American singer-songwriter Taylor Swift. Written by Swift and Liz Rose, the song was first produced by Swift and Nathan Chapman for her fourth studio album, Red (2012). After a 2019 dispute regarding the ownership of Swift's masters, she re-recorded the song as "All Too Well (Taylor's Version)" and released an unabridged "10 Minute Version" as part of the re-recorded album Red (Taylor's Version) in November 2021.

The lyrics of "All Too Well" narrate a failed romantic relationship, recalling the intimate memories and exploring the painful aftermath. The detail of a scarf that the narrator left at the house of her ex-lover's sister generated widespread interpretations and became a popular culture phenomenon. The 2012 version is a slow-burning power ballad combining styles of country and rock. The "10 Minute Version", produced by Swift and Jack Antonoff, has an atmospheric pop rock production. She performed the song at the 2014 Grammy Awards and included it in the set lists for two of her world tours: the Red Tour (2013–2014) and the Eras Tour (2023–2024).

"All Too Well" charted in Canada and the United States in 2012, and the "Taylor's Version" re-recording peaked atop the Billboard Global 200 and became the longest song to top the US Billboard Hot 100. The song also charted at number one in Australia, Canada, Ireland, Malaysia, New Zealand, and Singapore. Rolling Stone included it at number 69 in their 2021 revision of the 500 Greatest Songs of All Time. Critics praised the "10 Minute Version" for providing a richer context with its additional verses. The short film version of this re-recording received a Grammy nomination for Song of the Year at the 65th Annual Grammy Awards. Swift directed All Too Well: The Short Film to accompany it, which won the Grammy Award for Best Music Video.
