Taylor Swift has shared more detail about the ideas behind I Knew It, I Knew You, the song she wrote for Toy Story 5. During a recent country-radio appearance, Swift explained how she built several lyrics to carry more than one meaning while still connecting closely to the film’s emotional themes.
One example is the opening use of the word daze, which can also sound like days. Swift said the phrasing was meant to reflect the dreamy, blurred quality of childhood memories and the way certain moments can stay with people long after they happen.
The song focuses on friendship, separation, memory, and the feeling of reconnecting with someone who was once an important part of your life. Those ideas also fit naturally with the long-running Toy Story story world.
I Knew It, I Knew You has also given Swift a notable return to country radio. Released in June 2026, the track became her first Country Airplay top 10 since Red in 2013 and became the first song by a woman to debut inside the chart’s top 10.
