context_page_description: Adult Contemporary is a chart published by Billboard ranking the top-performing songs in the United States in the adult contemporary music genre. In 1980, 20 songs topped the chart, based on playlists submitted by radio stations.
  The first number one of the year was "Send One Your Love" by Stevie Wonder, which retained its position from the final chart of 1979, and held the top spot for the first two weeks of 1980. In the issue of Billboard dated January 19, it was replaced at number one by "Déjà Vu" by Dionne Warwick, who would return to the number one position in the fall with "No Night So Long" and was the only act to achieve more than one AC chart-topper in 1980. Solo vocalists dominated the top of the chart during the year; male soloists spent 21 weeks at number one and female soloists 20 weeks. The remainder of the year featured a duet between female singer Teri DeSario and KC, lead vocalist of KC and the Sunshine Band, and just two chart-toppers by groups. Three of the year's AC number ones also topped Billboard's all-genres chart, the Hot 100: "Woman in Love" by Barbra Streisand, Olivia Newton-John's "Magic", and "Lady" by Kenny Rogers.
