Cher's iconic hit turns heads at 80

Cher's 1998 hit song 'Believe' reached number one in more than 20 countries including Australia, selling 10 million copies worldwide and winning the Grammy for Best Dance Recording. The famous auto-tune vocal effect used in the song was kept secret by producers until its release to prevent other artists from copying the technique. The song is being celebrated as Cher marks her 80th birthday.See omnystudio.com/listener for privacy information.
