This is the one that started it all and launched Taylor's career in music. Although it's not the one that made her really popular, the name Taylor Swift finally became known in the public music scene. And who should we credit this song with? A guy named Brandon Borello. She's T-Swift's ex-boyfriend whom Taylor wrote the song "Tim McGraw" when he was about to leave for college. She said that she wanted him to think of her whenever he hears a Tim McGraw song. Apparently, "Our Song" was also made for him!
