"Emotion" is a song written by Barry and Robin Gibb. It was first recorded by Australian singer Samantha Sang, whose version reached number three on the Billboard Hot 100 chart in 1978. The Bee Gees recorded their own version of the song in 1994 as part of an album called Love Songs which was never released but it was eventually included on their 2001 collection titled Their Greatest Hits: The Record. In 2001, "Emotion" was covered by the American R&B girl group Destiny's Child. Their version of the song was an international hit, reaching the top ten on the US Hot 100 chart and peaking in the top five on the UK Singles Chart.

Originally, the song "Emotion" was recorded by Samantha Sang for the label. The song was Sang's only hit single, reaching number 3 on the Billboard Hot 100. Billboard ranked her version as the No. 14 song for 1978. There is a promotional video made for this song.

When Sang arrived in Miami, instead of recording "Don't Throw it All Away", Barry Gibb offered her a new song "Emotion". On this track, Sang sticks to a breathy, Barry-like sound. Gibb himself provided harmony and background vocals, using his falsetto on this track. The B-side was "When Love Is Gone," a Frances Lai composition. It was recorded around April 1977 in Criteria Studios in Miami, Florida around the same time as Barry contributed writing and producing "Save Me, Save Me" for the band Network. Blue Weaver identified the musicians as shown from memory. On the session, Joey Murcia plays guitar, George Bitzer on keyboards, Harold Cowart on bass and Ron "Tubby" Zeigler on drums. It was originally intended for use in the 1977 film Saturday Night Fever, but ended up being featured in the film The Stud (1978) starring Joan Collins. Also in 1978, Emotion was used as the B-side of Johnny Mathis and Deniece Williams's single "Too Much, Too Little, Too Late", which reached number one in the US.
