As a solo artist, Cher has sold 100 million records worldwide (in addition to 40 million as Sonny & Cher), making her one of the best-selling music artists of all time. She is one of the few artists to win three of the four major American entertainment awards (EGOT—Emmy, Grammy, Oscar, and Tony), and one of five actor-singers to have had a US number-one single and won an acting Academy Award. Her breakthrough single, Sonny & Cher's "I Got You Babe", is a Grammy Hall of Fame inductee and was featured on "Rolling Stone" "500 Greatest Songs of All Time" list compiled in 2003. Her 1971 single "Gypsys, Tramps & Thieves" was called "one of the 20th century's greatest songs" by "Billboard" magazine. Her 1998 song "Believe" is the biggest-selling single of all time by a female artist in the UK. It was voted the world's eighth favorite song in a poll conducted by BBC in 2003—the only American song to be named on the list. In 1988, she became the first performer to receive an Academy Award for acting and a RIAA-certified gold album in the same year since the inception of gold awards in 1958.
