A technological breakthrough altered how Billboard determined what was popular.

Billboard began incorporating streaming in 2007

For nearly 50 years, the Billboard charts primarily relied on radio airplay and retail sales. But in 2007, the magazine began incorporating early streaming services AOL Music and Yahoo! Music into its methodology, and later worked with Spotify, YouTube, and other platforms. A single stream was not weighed as heavily as a purchase of a physical CD or vinyl record. Still, streaming’s impact became evident when songs with minimal radio airplay began climbing the charts, as seen with Baauer’s “Harlem Shake,” which did exceptionally well on YouTube.

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

Billboard introduced its Modern Rock Tracks chart in 1988, looking to capture the rising popularity of acts like the Cure, REM, and U2. Music writer and Billboard obsessive Chris Molanphy traces the chart from his earliest days through grunge, alternative, and corporate eras, demonstrating just how much taste changes over time.

Billboard began as an advertising industry magazine

The magazine was initially “devoted to the interests of advertisers, poster printers, bill posters, advertising agents & secretaries of fairs.” While it occasionally tracked music via sheet music, record, and jukebox sales through the 1930s, it added its first true top 10 singles chart in 1940.

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 say comparing chart rankings across decades is meaningless

Although Billboard’s charts are presented as objective measures of a given song’s popularity, the company’s changing methodology (alongside changes in technology and listener habits) has made weighing chart success from different eras an imperfect science.

YouTube no longer provides data to Billboard

Billboard began using data from YouTube in 2013, tracking the platform’s most popular songs as it became a hub for listeners. That relationship ended in January 2026, when YouTube announced it was ending the partnership, citing a disagreement over how Billboard weighted premium users more heavily than free users.

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.

Billboard's early music charts were racially segregated

In 1942, the publication introduced the Harlem Hit Parade chart, listing the top 10 records sold at select record stores in the majority-Black borough of New York. In 1945, it changed the chart’s name to Most Played Juke Box Race Records, using the music industry term (“race record”) that identified recordings by Black artists, even if they played music markedly similar to the white artists on the other charts.

Bands largely disappeared from the charts in the 21st century

Chris Dalla Riva analyzed 65 years of Billboard charts and found that bands (even those that don't play instruments) severely declined in the 21st century, largely replaced by solo artists.

TikTok's algorithm has changed the way hits are made

Songs aimed at TikTok's algorithm—designed for viral dances or soundtracking common experiences—often find success on the Billboard charts. An early example was Lil Nas X's "Old Town Road," which used his memes and a country-trap beat from the Netherlands to rise to the top of the Billboard charts.

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.

How 'Nevermind' realigned the music industry

Nirvana's breakout album inspired other major labels to hunt for similarly loud, countercultural bands. That led to a fascinating period in popular music that found defiantly anticommercial indie acts like the Melvins, the Butthole Surfers, and Ween (among many, many others) suddenly offered lucrative contracts.

Billboard's first No. 1 single was Tommy Dorsey Orchestra's 'I'll Never Smile Again'

The song was No. 1 on Billboard’s Best Selling Retail Records chart, the predecessor to the Hot 100. The chart only measured record copies sold, excluding other indicators of popularity, like sheet music sales or jukebox plays, that were used on other charts.

Hip-hop gained significant popularity in the 21st century, dominating Billboard's pop chart.

In 2025, 'Walk My Walk' by Breaking Rust, an AI-generated artist, topped a Billboard country chart.

Although no longer the dominant format, CDs are increasingly popular with younger people

The compact disc now only accounts for about 3% of all music industry revenue, but those who still purchase CDs are, generally, much younger than most would expect. A 2023 YouGov poll found that 53% of Americans were willing to pay for music on CDs. When broken down by generation, those under 45-years-old were more likely to express interest in CDs and vinyl.

Biz Markie's "Alone Again" changed the laws for sampling

Before 1991, there was no established legal standard for the gray area of sampling. That changed when Gilbert O-Sullivan sued Biz Markie for using his song "Alone Again (Naturally)." After the case, labels were required to clear all samples, and artists were discouraged from creating sample-heavy music.

Country's popularity skyrocketed in the 21st century

Thanks to the crossover success of '90s artists like Garth Brooks and Shania Twain, country music found a larger audience. By the 2000s, the genre was more popular than ever, at times accounting for nearly a quarter of the Billboard Hot 100 chart.

'The Life of a Showgirl' was Swift's 15th chart-topping album

That places her second on Billboard's all-time list, though streaming has significantly changed how "sales" are interpreted. Prior to the shift to digital music, Billboard's album chart relied solely on sales of physical units. Since 2014, the chart has also considered streams from services like Spotify, Apple Music and YouTube.

Taylor Swift influenced record labels to change the way they write contracts

In addition to being a successful songwriter, Taylor Swift is a change-maker in the music industry. She asserted creative control over her music, re-recording her earlier albums after she lost the rights to them, and sparked a vinyl revolution in a digital age.

Superfans of K-pop group BTS gamed the Billboard chart

In 2021, the boy band scored a number one hit with “Butter,” its second English-language track. As Stereogum writer Tom Breihan points out, though, it rose to the top of the charts without actually being the most popular song in the country. Other songs were considerably more popular on streaming platforms, but BTS’ hyperdevoted fanbase realized that purchasing digital downloads weighed more heavily in Billboard’s methodology. Recognizing an opportunity, BTS dropped the price of a download to 69 cents, securing their place on the top of the charts.

Country music is having a moment. In 2023, it saw the biggest growth in market share of any genre—up nearly 22%. This overview traces country’s rise from Appalachian folk roots to its current pop, rock, and hip-hop-infused wave, with artists like Beyoncé and Post Malone joining the mix.

2025 marked the first time in 35 years a hip-hop song wasn't in the top 40

The Billboard Hot 100 chart dated October 25, 2025, didn't have any rap or hip-hop songs in its top 40 singles, something that hadn't happened since Feb. 2, 1990. One explanation is a Billboard methodology change, and another is Taylor Swift's "The Life of a Showgirl."

The most popular drum sound of the 1980s was discovered by accident

You know it when you hear it: the distinct snare drum of songs like Phil Collins' "In the Air Tonight" or Bruce Springsteen's "Born in the USA." It's called "gated reverb," and it's something most people associate, for better or worse, with the sound of the '80s. This Vox explainer breaks down how it was discovered by accident, thanks to a microphone typically used for communication that picked up additional sounds.
