The digital music landscape is currently defined by a high-stakes standoff between the world’s largest streaming platforms and the creative engine of the industry: songwriters and music publishers. At the heart of this conflict is a $500 million discrepancy—a massive shortfall in mechanical royalty payments that the National Music Publishers’ Association (NMPA) claims has been siphoned away since Spotify and Amazon transitioned their standalone music subscriptions into bundled service plans.
What began as a corporate strategy to increase subscriber retention and diversify service offerings has, according to industry analysts and legal experts, effectively eroded the mechanical royalty pool. By reclassifying music subscriptions as part of broader bundles that include other media—such as audiobooks—these platforms have fundamentally altered the mathematical formula that dictates how much songwriters are paid.
The Anatomy of a $500 Million Shortfall
The core of the issue lies in the complex, multi-tiered formula used to calculate royalties. Mechanical royalties—the payments made to songwriters and publishers for the reproduction of their musical compositions—are governed by a rigorous regulatory framework. When Spotify and Amazon rolled their paid music subscribers into bundled plans, they effectively shifted the revenue attribution model.
An analysis by Billboard, supported by data from the Manatt Music Streaming Royalty Calculator, reveals the stark reality of this shift. Between the fourth quarter of 2023 and the fourth quarter of 2025, the blended per-stream mechanical rate on Spotify’s paid subscriber tiers plummeted by approximately 51%. During that same window, the overall dollar payments for those licenses declined by nearly 45%.
To put this in perspective: in Q4 2023, the mechanical per-stream rate stood at approximately $0.00068. By Q4 2025, that figure had been slashed to $0.00033. In raw dollar terms, the mechanical payout dropped from roughly $97.3 million to $53.3 million over the two-year period. While the total volume of streams increased—growing by nearly 19.3 billion streams—the revenue generated by those streams failed to keep pace, leaving songwriters and publishers to bear the brunt of the "bundled" economy.
A Chronology of the Bundling Conflict
The seeds of this dispute were sown as streaming services looked for ways to combat market saturation. By folding audiobooks into the core Spotify experience, the company aimed to increase the "stickiness" of its platform. However, the legal and financial ramifications were immediate.
- Pre-2024: The industry operated under a structure where music revenue was calculated against a clear "headline rate," typically 15.25% of total revenue.
- March 2024: Spotify officially initiated its broad-scale bundling strategy. The NMPA and other industry bodies began tracking the immediate dip in reported mechanical royalties.
- Late 2024–2025: The discrepancy between streaming volume and royalty payments widened. The NMPA publicly highlighted the estimated $500 million loss at their annual meetings.
- January 2026: The Copyright Royalty Board (CRB) initiated the "Phono V" rate determination process, covering the period from 2028 to 2032. This proceeding has now become the primary battleground for the bundling dispute.
- March 2026: Spotify’s 6-K financial filing acknowledged a potential liability of 410 million euros ($471 million) should the Mechanical Licensing Collective (MLC) succeed in its ongoing litigation regarding the bundling practices.
The Mechanics of the Math: Why Revenue Attribution Matters
To understand why bundling costs songwriters so much, one must look at the "all-in pool" formula. This formula dictates that the mechanical/performance royalty pool must be the greater of either the headline rate (15.25% of revenue) or a percentage of the total content cost (the royalties paid to record labels).
When a service is a "music-only" subscription, the revenue is 100% music. However, when that subscription is bundled with audiobooks, the DSP can attribute a portion of that subscriber’s fee to the other media. If the total revenue attributed to music drops—for example, if only 52.6% of a bundle is considered "music revenue"—the 15.25% headline rate is applied to a significantly smaller base.
Furthermore, a "rate floor" exists: 33 cents per qualified subscriber. In 2023, this floor was rarely triggered because the revenue-based pool was higher. By 2025, however, with 20 different tiers, the floor became the dominant payout mechanism for many tiers, including some of the largest ones. This effectively "capped" the upside for creators, ensuring that even as the platform grew, the payouts to songwriters remained artificially suppressed.
Official Responses and the "Good Faith" Debate
Industry leaders have not remained silent. Jordan Bromley, the entertainment group leader at Manatt, Phelps & Phillips, labeled the current data a "wake-up call" for the entire songwriting community. "Mechanical royalties have dropped dramatically over the past two years, not because music is being played less, but because of fundamental changes in how these royalties are calculated," Bromley stated.
Conversely, Spotify has historically maintained that its global payments to the publishing sector continue to grow year-over-year. While they have declined to comment specifically on the recent analysis, the company has begun exploring "direct deals" with major publishers and the NMPA. These deals, covering rights for video and lyrics that fall outside the standard compulsory mechanical license, are intended to provide additional revenue streams.
Some independent publishers have characterized these direct deals as a "good faith" effort to restore some of the lost value. Others are more skeptical, arguing that Spotify is simply paying for additional rights to compensate for the mechanical losses, which they believe should have been paid out under the primary license anyway. An NMPA spokesperson emphasized this distinction, noting that "income from video should be on top of what Spotify must pay for interactive streaming—not instead of."
Broader Implications for the Future
The implications of this dispute extend far beyond a single ledger entry. We are witnessing a fundamental shift in the composition of songwriter income. As the NMPA’s Danielle Aguirre pointed out, the balance between performance and mechanical royalties has shifted from a 55/45 split to a 53/47 split in favor of performance, which, unlike mechanicals, often involves administrative fees or commissions from Performance Rights Organizations (PROs).
The "Phono V" proceedings represent a pivotal moment. The NMPA is pushing for regulatory guardrails to ensure that DSPs cannot manipulate the definition of "revenue" through bundling to the detriment of creators. For the thousands of working songwriters who rely on these payments, the outcome of these negotiations will determine whether the streaming era continues to reward the creation of music or whether it merely rewards the bundling of it.
As the industry looks toward the next cycle of royalty determinations, the message from the publishing community is clear: the current model is broken, and unless the "bundle" is treated with the transparency and fairness required by law, the creative class will continue to pay the price for corporate convenience. The fight for the next half-billion dollars—and the protection of the half-billion already lost—will define the next era of music economics.
