Rock Is on the Rise, While Pop Drops
“Rock posted the clearest gain of any genre in Radio Songs between 2021 and 2025, rising from 10% to 24% and more than doubling its footprint by the end of the period,” ChartCipher found.
Standout examples of rock hits that scaled Radio Songs in that span include sombr’s “Back to Friends,” Hozier’s “Too Sweet” and Glass Animals’ “Heat Waves.” (ChartCipher’s definition of rock includes alternative.)
Meanwhile, rock’s ascent “stands in sharp contrast to pop, which fell from 52% in 2021 to 35% in 2025 after peaking at 55% in 2022,” ChartCipher stated. Still, pop “remained the most represented genre for most of the period.”
Plus, “Country was comparatively steady, moving from 31% to 29% and briefly overtaking pop in 2024 at 33% versus 32%.”

Recapping the five most prominent primary genres for 2025 among Radio Songs hits: pop, 35%; country, 29%; rock, 24%; hip-hop/rap, 20%; and dance/club/electronic, 6%.
In 2021, the top five were: pop, 52%; country, 31%; hip-hop/rap, 20%; rock, 10%; and R&B/soul, 6%.
Drum and Bass Were Nearly Universal
What instruments were most commonly heard in Radio Songs hits over the last five years?
“Prominent drums and bass were nearly universal across the entire period,” ChartCipher compiled, with the instruments claiming nearly identical shares of between 93% and 96%.
As rock gained, “Guitar slightly grew from 60% in 2021 to 68% in 2025.
“Piano, on the other hand, moved in the opposite direction, falling sharply from 35% in 2021 to just 11% in 2025 — a drop of nearly two-thirds,” per Chart Cipher.
Still, hits by piano men — and women — in that stretch included Olivia Dean’s “Man I Need,” David Guetta and Bebe Rexha’s “I’m Good (Blue)” and Justin Bieber’s “Holy,” featuring Chance The Rapper.
Most Common Lyrical Moods Revealed
“The two most prevalent lyrical moods in every year of the five-year period were cynical and detached,” according to ChartCipher. Further, “The largest increases between 2021 and 2025 came from cynical and detached, which rose by 29 and 19 percentage points, respectively, to 75% and 57%.”
Plus, “anger increased by 16 percentage points to 40%.”

Wait, there’s positive news! ChartCipher reported that happy (38%) and optimistic (37%) rose to their highest shares of the five-year measurement in 2025, alongside the moods noted above. Especially happy hits on Radio Songs in that span include ROSÉ and Bruno Mars’ “APT.,” Nicky Youre and Dazy’s “Sunroof” and, naturally, Post Malone’s “I Like You (A Happier Song),” featuring Doja Cat.
