About 22

"22" is a song by the American singer-songwriter Taylor Swift from her fourth studio album, Red (2012). It was released as the album's fourth single on March 12, 2013, by Big Machine Records. Written and produced by Swift, Max Martin, and Shellback, "22" combines pop subgenres such as bubblegum pop and dance-pop with disco and 1990s rock. The track begins with an acoustic guitar riff and progresses into an upbeat refrain which incorporates pulsing synthesizers and syncopated bass drums. The lyrics celebrate being 22 years old while acknowledging the heartache that the narrator experienced in the past.
