"Once a Day" is a song written by Bill Anderson and recorded as the debut single by American country artist Connie Smith. It was produced by Bob Ferguson for her self-titled debut album. The song was released in August 1964, topping the Billboard country music chart for eight weeks between late 1964 and early 1965. It was the first debut single by a female artist to reach number one on the Billboard Hot Country Songs. This song peaked at number one for the week of November 28, 1964, and it stayed at number one for eight consecutive weeks, a record for a female solo artist for nearly 50 years, until it was surpassed by Taylor Swift's "We Are Never Ever Getting Back Together" in December 2012.

"We Are Never Ever Getting Back Together" is a song by the American singer-songwriter Taylor Swift and the lead single from her fourth studio album, Red (2012). Big Machine Records released the song for download and to U.S. pop radio on August 13, 2012. Written and produced by Swift, Max Martin, and Shellback, "We Are Never Ever Getting Back Together" is an upbeat incorporation of many pop styles. Its production contains pulsing synthesizers, processed guitar riffs, bass drums, and a spoken-word bridge. Its lyrics express Swift's frustration with an ex-lover who wants to rekindle their relationship. An alternate version was released to U.S. country radio on August 21, 2012.
