Fearless. Taylor Swift's second studio album sold over half a million copies its first week of release when she released it back on November 11, 2008. And we're taking a look back at this album as it turns 10 years old this year. And this next song, it was so amazing because it was a song that she wrote for her mom. And in fact, it was a total surprise. The best day is a song that I wrote without telling my mom. I wrote it in the summertime, and I recorded it secretly too. And I had this idea that I wanted to play it for her for Christmas. And so when I got the track, I synced up all these home videos from when I was a little kid to go along with the song like a music video and played it for her on Christmas Eve. And she was crying her eyes out. I can only imagine this is the best day on big machine radio.
