The No. 1 spot on Billboard’s Hot 100 is sought after by emerging and established artists alike, and an appearance in that position indicates that a song is a bona fide big hit.
To identify the biggest hit singles of 2021 so far, 24/7 Tempo reviewed the tracks that peaked at No. 1 at least once this year on Billboard’s Hot 100 chart, as of September 25, 2021. The 23 songs on this list are ranked by their number of weeks at No. 1. Each song’s total number of weeks on the Hot 100 is also included.
Newer artists to top the charts include breakthrough singer-songwriter Olivia Rodrigo and the Korean pop band BTS. Rodrigo had two singles achieve the top spot — “good 4 u” and “Driver’s License” — both acclaimed for their evocative melodies and powerful vocals.
BTS was formed in 2010, but released their first entirely English language song, “Dynamite,” only in 2021. This was followed by two more English-language songs, all three of which reached No. 1. (See the artists with the most No. 1 hits.)

The Weeknd broke records for his song “Blinding Lights,” which impressively remained in the Billboard’s Top 10 for 90 straight weeks. Mariah Carey broke a different record when her holiday classic “All I Want for Christmas,” topped the charts for the fourth consecutive year — despite having been released originally in 1994. (These are the most popular hit singles of the 21st century.)

> Artist: Harry Styles
> Weeks at No. 1 in 2021, as of Sep 25: 2
> Weeks on Hot 100 chart in 2021, as of Sep 25: 39
Styles wrote this funk-pop song in 2017 about his ex, who is a fan of the post-apocalyptic novel “In Watermelon Sugar” by Richard Brautigan.

> Artist: Mariah Carey
> Weeks at No. 1 in 2021, as of Sep 25: 2
> Weeks on Hot 100 chart in 2021, as of Sep 25: 44
Mariah Carey is making history as her single debuts on the Hot 100 for the fourth consecutive year. Surprisingly, it topped the Billboard charts for the first time in 2019, which was 25 years after its 1994 release. This is attributed to a large push from fans on streaming platforms. She released a music video in 2019 to celebrate the festive song’s revival.
20. WAP
> Artist: Cardi B Featuring Megan Thee Stallion
> Weeks at No. 1 in 2021, as of Sep 25: 5
> Weeks on Hot 100 chart in 2021, as of Sep 25: 24
This groundbreaking song explicitly discusses how Cardi B and Megan want men to please them. While many saw the song as a celebration of feminitiy and sex positivity, more conservative commentators found the song to be problematic. Either way, it was extremely successful. Not only did it become the first No. 1 single on the Billboard Global 200 when the chart was introduced last fall, but it also was named the best song of the year by Pitchfork, Rolling Stone, and NPR, among others.

19. Savage Love (Laxed – Siren Beat)
> Artist: Jawsh 685 x Jason Derulo
> Weeks at No. 1 in 2021, as of Sep 25: 5

Derulo sampled an instrumental beat by Jawsh 685, which the artist posted to YouTube in 2019. However, when Derulo originally released “Savage Love,” he didn’t ask permission to use the beat or credit its source. This created media backlash, but the issue was ultimately resolved, with Jawsh 685 receiving proper acknowledgement. The song became a viral TikTok trend and went on to be Derulo’s second No. 1 Billboard song, and Jawsh 685’s first.
