AceShowbiz - Sony Music Publishing completed a remarkable achievement in 2025 by securing the No. 1 position as the leading music publisher across all four quarters of the year. This continuous dominance was confirmed in the final quarter, where Sony clinched the top spots in both the Radio Airplay and Billboard Hot 100 publisher rankings, solidifying its presence as the industry’s foremost powerhouse.

Following its No. 1 placement in the first three quarters of 2025, Sony extended its lead in the last quarter by capturing a commanding 30.3% share of the Radio Airplay rankings. This figure was nearly eight percentage points ahead of its closest competitor, Warner Chappell Music, which earned 22.13%. On the Billboard Hot 100 publisher chart, Sony narrowly outpaced Kobalt, achieving a 21.57% market share compared to Kobalt’s 21.43%, thus completing a clean sweep of both rankings for the entire year.

Among Sony’s standout contributors in Q4 was the songwriter Shane "sombr" Boose, who emerged as the top Radio Airplay songwriter for the quarter. Boose, who is represented by Sony through Songs of Orchard, was the sole writer behind two notable Radio Airplay charting songs: "Back to Friends," ranking No. 9, and "Undressed," placing No. 78. These successes contributed significantly to Sony’s commanding market share in radio play.

The Radio Airplay chart also featured a noteworthy tie for the No. 1 songwriter spot among the collaborators on Taylor Swift’s acclaimed album, The Life Of A Showgirl. This album’s 12 tracks were predominantly written by Swift herself, along with Max Martin and Shellback, with only one song involving an additional co-writer. All 12 songs made the Hot 100 chart in the fourth quarter, with 11 landing in the top half. The album’s lead single, "The Fate Of Ophelia," ranked as the No. 1 song for the quarter. Notably, Swift is represented by Universal Music Publishing Group, whereas Max Martin and Shellback are affiliated with Kobalt.

In terms of song placements on the Radio Airplay chart, Sony maintained a strong presence with 75 songs in Q4, matching its prior quarter count. However, its market share slightly dipped from 30.76% in Q3. Sony’s highest-ranking song on this chart was Leon Thomas’ "Mutt," which claimed the No. 1 position for the quarter. On the Hot 100, Sony’s representation declined from 69 songs in Q3 to 49 in Q4, accompanied by an eight percentage point drop in market share, from 30.10% to 22.10%. The publisher’s top Hot 100 song was Alex Warren’s "Ordinary," which reached No. 3 on the chart.

Warner Chappell Music secured the No. 2 spot on the Radio Airplay chart for the ninth consecutive quarter, with a 22.13% market share and 57 song placements, including involvement in the quarter’s No. 2 song, "Ordinary." Although its placements and share were down from 64 songs and a 23.67% share in Q3, Warner Chappell maintained its strong runner-up position. However, on the Hot 100 chart, Warner Chappell dropped from No. 2 to No. 3, as its market share decreased from 22.32% to 16.92%, and its song count fell from 52 to 36.

Universal Music Publishing Group ranked third on the Radio Airplay chart with a 13.92% share, slightly lower than its 14.79% in Q3. Despite this, Universal improved its Hot 100 market share to 16.69% in Q4, but remained in fourth place on that chart. The publisher’s top Radio Airplay song was Justin Bieber’s "Daisies," positioned at No. 3 on the chart, among 44 total placements. On the Hot 100, Universal had 47 song placements, including the Taylor Swift tracks, with "Ophelia" as its highest-ranking song.

Kobalt ranked fourth on the Radio Airplay chart with an 11.59% share and 40 song placements, including “Mutt.” However, it surged to No. 2 on the Hot 100 chart by reaching a 21.43% share with 43 song placements. This marked Kobalt’s highest Hot 100 publisher ranking since Billboard began tracking in 2019 and its first time surpassing the 20% market share milestone since 2006, when Radio Airplay rankings for publishers started.

BMG secured the No. 5 ranking on both the Radio Airplay and Hot 100 charts, with a 6.23% share on Radio Airplay from 14 songs and an 8.15% share on the Hot 100 from the same song count. Its leading song on both charts was "Golden" from the KPop Demon Hunters soundtrack, which ranked No. 4 on Radio Airplay and No. 2 on the Hot 100.

The latter half of the Radio Airplay top 10 included Concord at No. 6, Spirit at No. 7, Position Music at No. 8, and Big Machine at No. 10, all maintaining their Q3 rankings. Concord was the only publisher to improve its market share, rising from 1.40% to 2.36%, which elevated it from eighth to sixth place. Reservoir re-entered the top 10 at No. 9 with a 1.19% share after missing out in the previous two quarters.

On the Hot 100 chart, Concord was the sole publisher to retain its position from Q3, holding No. 7 with a 2.05% market share — nearly doubling its previous 1.07%. New entries for Q4 included St. Nicholas Music at No. 6, a seasonal presence due to its representation of Johnny Marks, the legendary Christmas songwriter. Peermusic, Round Hill Music, and Tamir Music rounded out the No. 8 to No. 10 positions. Tamir Music made its debut thanks to its stake in Eartha Kitt’s classic "Santa Baby," performed with Henri Rene and His Orchestra.
