Songwriter Liz Rose still remembers sitting down with Taylor Swift to pen the singer's No. 1 smash hit 'You Belong With Me' like it was yesterday.

"We wrote it on a Saturday," Rose tells Taste of Country. "She called me and said, 'I'm finishing the record ... let's write a song.' She came in talking about a friend of hers ... something about him talking about his girlfriend on the phone. And she just starts telling you a story, and then she picks up a guitar and goes [starts singing the opening verse]."

"You're on the phone with your girlfriend, she's upset / She's going off about something that you said / 'Cause she doesn't get your humor like I do / I'm in the room, it's a typical Tuesday night / I'm listening to the kind of music she doesn't like / And she'll never know your story like I do," Swift sang.

"I think it was [originally] going to be Friday, but she goes, 'No, let's do Tuesday, because Tuesday's so not typical! Everybody would say Friday or Saturday, so let's say Tuesday,'" Rose recalls of the verse's lyrics. "I just write it down as fast as I can, and say, 'Wait a minute ... I think this is what you said? What if we said this?' That's how we write."

"If you could see that I'm the one who understands you / Been here all along, so why can't you see? / You belong with me," they wrote for the chorus.

"When I write with other people, I'm the lyrics," notes Rose. "They start playing music, and lyrics just start coming out [of me]. With Taylor, it's everything, and we just kind of bounce off each other. I think it's faster. She's brilliant, and she deserves everything. For her, though, it's always been about the songs. It's never 'I'm going to be a star.' It's 'I'm going to be a great songwriter.' I know everybody knows how brilliant she is, but I just have to always tell people how freakin' brilliant she is [laughs]!"
