Some critics say comparing chart rankings across decades is meaningless

A century of Billboard issues documenting the evolution of popular music.

Billboard’s Hot 100 methodology is notoriously private

The magazine’s singles chart is based on on-demand streams (from platforms like Spotify), digital sales (from stores like iTunes), and radio airplay. Not all of those sources are weighted equally, though—sales are more important than airplay, and airplay is more significant than streams. In 2018, Billboard began weighing streams from premium subscriptions more heavily than free streams (like listening to a song on Pandora).

One writer traces the evolution of a Billboard chart over 25 years

Several major artists have embraced manipulating the Billboard charts

Billboard is supposed to be an accurate, objective representation of the country’s listening habits, but artists and their fans have discovered ways to manipulate the magazine’s methodology in order to push tracks to the top of the charts. In 2018, Taylor Swift rewarded fans for purchasing her album multiple times; in 2020, Justin Bieber reposted suggestions that fans repeatedly stream one of his songs while they sleep.

Some critics argue that Grammys favor commercially successful artists

For this two-part series of Slate’s pop music podcast "Hit Parade," pop critic Chris Malanfi looks into the relationship between commercial and critical success and how the Grammys are affected by outside influences like the Billboard Hot 100 chart.

A technological breakthrough altered how Billboard determined what was popular

Before 1991, retail stores manually reported sales to Billboard, which then used those figures as part of its calculations for its weekly charts. In 1991, the magazine began using Nielsen SoundScan, a technology that tracked every unit sold in participating stores, providing a more accurate picture of what consumers were actually buying.

TikTok isn’t factored into a song’s rank on the Billboard charts, but it can have an impact

Billboard ranks a song’s chart position based on its radio airplay, its physical sales, and its streaming numbers (across Spotify and other platforms), but doesn’t include user-generated content, meaning it doesn’t include TikTok videos. Keith Caulfield, Billboard’s managing director of charts and data operations, notes that TikTok still has an impact, though, because listeners will often stream the app’s most popular songs on other platforms.

Author Malcolm Gladwell attempts to unpack the calculation, ultimately raising the question: How relevant is the list?

Although payola was made illegal in 1960, it likely continued on the Billboard charts through the '70s

In his book “Uncharted Territory: What Numbers Tell Us about the Biggest Hit Songs and Ourselves,” music journalist Chris Dalla Riva argues that payola, the music industry term for undisclosed paid publicity, likely continued into the 1970s with the Billboard chart. Dalla Riva cites chart irregularities and reports about Bill Wardlow, Billboard’s then director of sales, who was a known booster for disco label Casablanca Records.

Some critics argue bebop and free jazz led to jazz's decline in popularity

The double album was an ambitious collection of songs that traversed musical styles—drawing on the emerging hip-hop records of the genre's golden age and technological experimentation—and explored social issues, including the AIDS epidemic, addiction, and violence. It would go on to be one of the most critically acclaimed albums of the year and eventually be considered one of the most important in pop music history.
