Jake Gyllenhaal and Taylor Swift dated for three months. I'm not sure if you were aware of that.
The original version of this song, which pretty much covers that relationship, was a top 20 Country hit in 2013. It was from her Red album, which really sparked Taylor's transition from country to pop artist.
Famously, she's rerecording her Big Machine catalog and retaining control of her catalog. This version of "All Too Well" TOPPED the POP charts in November 2021. This ten minute version of the song, which is now the longest #1 song in history, was accompanied by this short film.
It was also accompanied by this SNL performance of the song. The performance was, in a word, great, and this is coming from someone who is NOT Taylor's biggest fan, like Scott Colvin.
