Breathe is a country pop song performed by American singer-songwriter Taylor Swift, featuring Colbie Caillat as the co-writer and backing vocals. The song was written by Swift and Caillat and produced by Nathan Chapman with Swift's aid. It is the seventh track from Swift's second studio album, Fearless (2008). The song was written about the end of a friendship. Musically, the song is driven by acoustic guitar.
The song received favorable responses from contemporary music critics. "Breathe" was nominated for the Grammy Award for Best Pop Collaboration with Vocals, but lost to Jason Mraz and Caillat's "Lucky". "Breathe" peaked at number eighty-seven on the Billboard Hot 100. Its appearance tied Swift with Hannah Montana (Miley Cyrus) for two records on the Billboard Hot 100.
On the week ending November 29, 2008, "Breathe" debuted and peaked at number eighty-seven on the Billboard Hot 100. Its appearance, along with six other songs, on the chart tied Swift with Hannah Montana (Miley Cyrus) for the female act to have the most songs charting on the Billboard Hot 100 in the same week, a record later surpassed by Swift herself when she charted eleven songs at once in 2010. It was also one of six songs to debut that tied her with Cyrus, again, for the most debuts on the chart in the same week. The song spent one week on the chart.
