Quick Scoop

  • Mariah Carey reached No. 1 in the 1990s, 2000s, 2010s and 2020s on the Billboard Hot 100, making her the first and so far only artist to do this.
  • The key song that completed her four-decade streak is her holiday classic “All I Want for Christmas Is You,” which finally hit No. 1 in 2019 and then returned to No. 1 again in early 2020, giving her hits in both the 2010s and 2020s.
  • News outlets highlighted this as a historic milestone, noting that while several legends have reached No. 1 in three different decades, Carey stands alone across four on the Hot 100.
