Their Greatest Hits: The Record is the career retrospective greatest hits album by the Bee Gees, released on UTV Records and Polydor in November 2001 as HDCD. The album includes 40 tracks spanning over 35 years of music. Four of the songs were new recordings of classic Gibb compositions originally recorded by other artists, including "Emotion", "Heartbreaker", "Islands in the Stream", and "Immortality". It also features the Barry Gibb duet with Barbra Streisand, "Guilty", which originally appeared on Streisand's 1980 album of the same name. It is currently out of print and has been supplanted by another compilation, The Ultimate Bee Gees.

"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. English singer Emma Bunton also covered the song on her 2019 album My Happy Place.
