Which song was the first by a solo female artist to spend at least 10 weeks at No. 1 on the Billboard Hot 100?

Debby Boone’s “You Light Up My Life” was the first song by a solo female artist to spend at least 10 weeks at No. 1 on the Billboard Hot 100.

The song led the chart for 10 weeks in 1977, becoming one of the defining hits of that year. It was written by Joe Brooks for the film of the same name, while Boone recorded the hit single version. Her performance earned a Grammy Award for Best New Artist.

The record’s long reign reflected the song’s broad adult-contemporary appeal and its prominent use in the film. It also became one of the best-selling singles of the 1970s in the United States.

The milestone concerns a solo female performer and a 10-week Hot 100 reign. It should not be confused with later female-led hits that stayed No. 1 longer, including Whitney Houston’s “I Will Always Love You.”
