Before T-Pain and Kanye, Cher introduced the technology to the masses – and the top of the Hot 100.
Twenty-five years after she had last topped the Billboard Hot 100, Cher scored her fourth No. 1 with "Believe" on March 13, 1999 -- setting the record for the longest gap between first-place finishes on the chart.
The California native's career began in the 1960s as a backup singer on a number of Phil Spector-produced recordings, but she found real fame as one-half of the husband-and-wife duo Sonny & Cher. The pair claimed five top 10 Hot 100 singles during a near-decade of hits, including the No. 1 "I Got You Babe" in 1965.
After she navigated a messy divorce in the mid-1970s, Cher emerged as a solo star. She tallied a total of 11 top 10 hits through 1988 and won the Academy Award for best actress for 1987's Moonstruck.
