The biggest hits on the Billboard Hot 100 also commonly scale both the Streaming Songs and Radio Songs charts.
The two titles to top the Hot 100 for double-digit weeks most recently fit that description, with Ella Langley’s “Choosin’ Texas” and Taylor Swift’s “The Fate of Ophelia” both No. 1s on Streaming Songs and top five hits on Radio Songs. Plus, Bruno Mars has led all three lists this year with “I Just Might.”
Still, sonic differences exist between hits on Streaming Songs and Radio Songs — along with commonalities.
ChartCipher has released its new trend report spotlighting performance on Streaming Songs and Radio Songs hits from 2021 through 2025, encompassing all titles, whether they peaked at No. 1 or No. 50. (“Using AI, ChartCipher extracts granular data for the compositional, lyrical and sonic qualities of songs and delivers insights into the qualities shaping today’s hits,” the company noted in the report.)
Below is a look at highlights of ChartCipher’s research, revealing how the charts align and how they diverge, and what they may indicate about hit music halfway through the decade.
What’s the Same About Hits on Streaming Songs & Radio Songs?
Pop Doubles on Top: In 2025, pop was the most common primary genre represented on both Streaming Songs and Radio songs. Over the past five years, pop has triumphed twice on Streaming Songs, leading over runner-up hip-hop/rap last year and in 2023. On Radio Songs in that span, pop posted four wins.

Swift, Justin Bieber and Tate McRae were among the pop torchbearers on the two charts over 2021-25, each with more than 10 entries on both Streaming Songs and Radio Songs.
Rock Climbing: In that stretch, noted ChartCipher, “Rock gained meaningful ground on both charts, from 10% to 24% on Radio Songs and from 10% to 20% on Streaming Songs” in terms of annual shares on each ranking. (ChartCipher’s definition of rock includes alternative.)
Love Lost: “Love has always been pop music’s go-to theme, but between 2021 and 2025 it lost ground on both charts,” ChartCipher reported. On Streaming Songs, love decreased from 51% to 42% showings. On Radio Songs, songs centered on love dropped from 48% to 40%.
Moodier Music: Alongside love losing ground in hits over 2021-25, moods such as detached, angry and reluctant gained, ChartCipher analyzed. Still (and, phew), “Optimistic and happy moods rose, too, though to lower peak levels.”
Steadily Slower: Perhaps unsurprisingly, per those last two points, both streaming and airplay hits grew progressively slower over the past five years. “Under 79 beats per minute became the most common tempo range on both charts,” according to ChartCipher. Plus, “it led on Streaming Songs every year.”
What’s Different About Hits on Streaming Songs & Radio Songs?
Radio More Receptive to Country: “Country has played a fundamentally different role on each chart,” ChartCipher noted about the genre over 2021-25. “It’s a reliable structural pillar on radio and a smaller and more volatile presence on Streaming Songs.” On the latter list, country’s representation as a genre “averaged 14% across the period.” On Radio Songs, it “held between 28% and 33% every year, never falling below second place” in its push-and-pull with pop; Pop led in 2021-23 and 2025, with country claiming top honors in 2024.
Keys to Success: Comparing major and minor keys in hits the last five years, “Radio Songs leaned major throughout the period, while Streaming Songs carried a heavier minor-key presence,” found ChartCipher. On Radio Songs, major keys had takes of 65-71% every year, reflecting radio’s “steady preference for the brighter tonal center that major keys provide.”

Notable (or, well, key) examples of major-key hits on Radio Songs in 2021-25 include Swift’s “Cruel Summer,” Luke Combs’ “Fast Car” and HUNTR/X’s “Golden.” Big (or, well, major) minor-key hits on Streaming Songs in that period include The Weeknd’s “Blinding Lights,” Jack Harlow’s “First Class” and Hozier’s “Too Sweet.”
Streaming Darker, Radio a Mix: “The tonal character of hits split clearly along chart lines,” ChartCipher stated. Over the measurement window, “Streaming Songs ran consistently darker, while Radio Songs spread more evenly between brighter and darker timbres.” On Streaming Songs, “Darker timbre ranged from 41% to 60%, consistently the dominant tonal character.” On Radio Songs, “Brighter and darker timbres traded the lead throughout the period, with neither exceeding 42%. No single tonal direction took over.”
Radio Edits: Radio has historically favored brevity in songs, so that quarter-hours contain variety (and commercials and jock content). Streaming is more open-ended, given its personalized form. As such, ChartCipher observes that “Streaming Songs consistently features a larger share of songs exceeding four minutes, reflecting the on-demand freedom from the time constraints that shape radio programming.”
More Repetition in Radio Lyrics: Also seemingly a byproduct of radio’s mass-appeal model, with earworms likely to be agreeable to many, over more individualized, on-demand-focused streaming, “The two charts show starkly different approaches to lyrical repetition,” ChartCipher notes. Over 2021-25, “Radio Songs concentrated in moderate repetitiveness, while Streaming Songs’ lyrics skewed toward lower repetition, a gap that has persisted throughout the entire period.”
Are the Charts Now More Similar or Different?
“The most consequential finding across this five-year analysis is not any single trend but the direction of movement between the two charts themselves,” ChartCipher theorized. “In 2021, the Radio Songs chart and the Streaming Songs chart presented meaningfully different compositional profiles. By 2025, that distance had narrowed considerably.”
ChartCipher found that streaming and radio hits essentially met in the middle in terms of leading genres. “On Streaming songs, the categories that once defined the chart’s identity eroded sharply,” the report stated. “Hip-hop/rap fell from 48% to 25% as a genre, but the 23 percentage points of share it gave up did not flow into pop alone. Instead, rock, Latin and country absorbed most of the loss, producing a more distributed genre landscape.
“Radio’s movement was the mirror image,” per ChartCipher. “Pop’s genre share dropped from 52% to 35%, with rock absorbing the bulk of the shift. The result was the same: a chart that entered the period with one genre holding a commanding lead and exited with a competitive, multi-genre field. The two charts did not converge because one adopted the other’s profile; both shed their dominant genre and arrived at a similar state of genre distribution from opposite starting points.”
Such shifts toward common ground — along with both charts’ drops in piano, gains for guitars and rise of rock as a genre — suggest, per ChartCipher, “that the forces shaping mainstream music were increasingly platform-agnostic.”
