It is included in the 3D movie of the tour, as well as in the soundtrack to the film.
"Should've Said No" was certified Gold by the RIAA on September 3, 2008.
The song is an up-tempo in which the central character addresses a former lover who has cheated on her, telling him that he "should've said no" to the female who has taken her place in his life ("You should've said no you should've gone home. You should've thought twice before you let it all go! Should've said no and Baby, and you might still have me").
Taylor Swift wrote the song when she was sixteen years old. According to Country Weekly magazine, she was inspired to write it after she had realized that her boyfriend at the time had cheated on her. The first line that came to her was the title. Most of the lyrics were based on the actual confrontation between the two as well, and she wrote the chorus in five minutes. Swift has also said that many of the lyrics were based on actual words that she used when confronting him. Taylor Swift also performs this song with The Jonas Brothers in their 3-D movie
