Infringement Without a Remedy: Eight Mile Style v. Spotify and the Estoppel Trap

A Tennessee court found Spotify infringed Eminem's compositions by streaming them without mechanical licenses, then barred the claim entirely under equitable estoppel for the publisher's strategic delay.

In Eight Mile Style, LLC v. Spotify USA Inc., No. 3:19-cv-00736 (M.D. Tenn. Aug. 15, 2024), U.S. District Judge Aleta A. Trauger delivered an unusual two-part verdict: Spotify had committed copyright infringement by streaming Eminem’s compositions without valid mechanical licenses — and yet the publisher could recover nothing, because equitable estoppel barred the claim. The decision is a cautionary study in how the mechanics of music licensing, the gaps in industry databases, and a rights-holder’s litigation timing can combine to extinguish even a meritorious infringement case.

Matter: Eight Mile Style, LLC v. Spotify USA Inc., No. 3:19-cv-00736
Forum: U.S. District Court for the Middle District of Tennessee (Judge Aleta A. Trauger)
Decided: August 15, 2024 (summary judgment for Spotify and the Harry Fox Agency)
Subject matter: The Section 115 compulsory mechanical license, the equitable estoppel defense in copyright, and the Music Modernization Act’s limitation on liability
Works at issue: Roughly 240 musical compositions popularized by Eminem, including “Lose Yourself”
Threshold finding: Spotify infringed — Kobalt lacked authority to license the compositions, and accepting royalties created no implied license
Dispositive holding: Claims barred by equitable estoppel because the publisher knowingly delayed suit to maximize statutory damages

How a licensing dispute reached the courthouse

Eight Mile Style and Martin Affiliated, LLC own and administer compositions written and recorded by Eminem — among the most valuable catalogs in modern hip-hop. They sued Spotify in 2019, alleging that the service had streamed those works since its 2011 U.S. launch without ever securing proper mechanical licenses, and that Spotify’s reproduction and distribution of the compositions therefore infringed.

The case became a vehicle for one of the era’s most contested statutory questions. The Music Modernization Act of 2018 sharply limited the liability streaming services face for past unlicensed reproductions, channeling many claims into the new blanket-license regime and curbing the statutory damages otherwise available. Eight Mile Style mounted a constitutional challenge to that limitation-of-liability provision, arguing it unlawfully stripped vested rights. The litigation thus carried implications well beyond Eminem’s catalog: it tested whether the MMA’s central bargain with rights-holders would hold.

The threshold ruling: Spotify infringed

Judge Trauger first addressed whether Spotify had any license at all. Spotify contended it was covered through Kobalt Music Publishing, from which it had licensed in 2016 in the belief that the Eminem compositions were included. The court rejected that defense. It found that Kobalt had neither actual nor apparent authority to license the U.S. mechanical rights to these compositions, which had been assigned for administration to Bridgeport Music. Nor did Eight Mile Style’s acceptance of royalties that flowed through the Kobalt arrangement create an implied license: there was no evidence the publisher intended to grant Spotify a free or standard-rate license by cashing those checks.

Having cleared away the license defenses, the court reached a threshold conclusion striking in its bluntness — Spotify had committed copyright infringement. For a plaintiff, that should have been the hard part. It was not the end.

The estoppel reversal: a meritorious claim, barred

The decisive issue was equitable. Relying on the Supreme Court’s confirmation in Petrella v. Metro-Goldwyn-Mayer, Inc. that equitable estoppel remains available as a defense in copyright cases even where the statute of limitations would not bar suit, Judge Trauger held that all four elements of estoppel were satisfied.

First, Eight Mile Style knew the facts — that Spotify was streaming its compositions — for years before filing. Second, the publisher intended that Spotify rely on its silence, or at least acted with culpable conduct: rather than promptly asserting its rights, it allowed the apparent licensing arrangement to continue. Third, Spotify lacked knowledge of the true facts, operating amid a registration tangle in which Kobalt had registered the compositions with the Harry Fox Agency in its own name back in 2009, even though the administration rights belonged to Bridgeport — a mistake none of the parties corrected. Fourth, Spotify relied to its detriment, continuing to stream and pay royalties into a system everyone believed was functioning.

The court’s framing was pointed. It found that the publisher had made a “strategic choice” to hold off suing in order to “manufacture infringement damages,” and that Eight Mile Style had effectively chosen “the cultivation of infringement damages over the proper functioning of the copyright system.” Equitable estoppel, Judge Trauger wrote, “disfavors that practice and, at least in this instance, forbids it.” In her account, the rights had “fallen into confusion,” and the publisher had patiently accumulated leverage under the Copyright Act’s generous damages provisions, planning to sue when most advantageous.

The constitutional question left for another day

Notably, the court declined to resolve the constitutional challenge to the MMA’s limitation-of-liability provision. Rather than reaching that merits question, the court treated the timing of the challenge as itself evidence of the strategic delay that grounded estoppel — and left “any decision regarding the MMA for a future case involving an appropriate plaintiff.” The most closely watched legal issue in the case thus remains open, awaiting a rights-holder whose conduct does not invite an equitable bar.

The summary judgment is on appeal to the U.S. Court of Appeals for the Sixth Circuit, where the estoppel ruling — and potentially the deferred MMA question — may be revisited.

Open questions

How far does estoppel reach in streaming disputes? If knowing delay plus database confusion can bar even a proven infringement claim, the defense may become a routine shield for services that paid royalties into a flawed system.
Will the MMA’s liability limit ever face merits review? By sidestepping the constitutional challenge, the court left the MMA’s central protection untested — and signaled that the wrong plaintiff can forfeit the chance to test it.
What duty do rights-holders have to police registrations? The decision implies that sitting on known infringement while databases misattribute administration can be culpable conduct, but the contours of that duty remain undefined.

Implications

Winning on infringement is not winning. A plaintiff can prove unauthorized reproduction and still recover nothing if equitable estoppel applies.
Litigation timing is now a liability. Delaying suit to inflate statutory damages can backfire into a complete bar under Petrella’s estoppel pathway.
Database accuracy is legally load-bearing. Misregistration at the Harry Fox Agency and confusion over who administers a catalog can defeat a rights-holder’s claim by making the licensee’s reliance reasonable.
The MMA’s liability shield endures untested. Its constitutionality survives by avoidance, not vindication — leaving uncertainty for the next dispute.
Watch the Sixth Circuit. Appellate review could narrow the estoppel holding or finally force the deferred MMA question.

Frequently asked questions

If Spotify infringed, why did Eight Mile Style lose? Because the court applied equitable estoppel. The publisher knew Spotify was streaming its compositions for years, allowed an apparent licensing arrangement to continue, and — in the court’s view — delayed suing to maximize damages. Spotify reasonably relied on that conduct, so the claim was barred despite the underlying infringement.

What role did the Harry Fox Agency and Kobalt play? Kobalt had registered the compositions with the Harry Fox Agency in its own name in 2009, even though administration rights belonged to Bridgeport Music. No one corrected the error, so when Spotify licensed through Kobalt it believed in good faith that the Eminem works were covered — confusion central to the court’s reliance finding.

Did the case decide whether the Music Modernization Act’s liability limit is constitutional? No. The court declined to reach the constitutional challenge, leaving that question “for a future case involving an appropriate plaintiff.” The MMA’s limitation-of-liability provision remains in force and untested on the merits in this litigation.
