Eminem Publisher Sues Suno for $41M, Alleging Copyright Infringement and Metadata Stripping

Eight Mile Style, the Ferndale, Michigan publisher that administers nearly 270 Eminem compositions, filed a federal lawsuit on November 6 against AI music generator Suno, seeking more than $41 million in damages. The 36-page complaint (the filed document; press reports described it as 32 pages), filed in the Northern District of California, alleges that Suno trained its models on “essentially all music files of reasonable quality that are accessible on the open Internet” — including Eight Mile Style’s catalog — without permission, and that it stripped embedded copyright management information (CMI) from those files during ingestion [6].

The publisher controls songs such as “Lose Yourself,” “Without Me,” “’Till I Collapse,” “The Real Slim Shady” and “Stan.” The suit claims statutory damages of $150,000 per work for 269 compositions ($40.35 million), plus $672,500 for alleged circumvention of technological protection measures under DMCA Section 1201, and $6,725,000 for CMI removal under DMCA Section 1202 [4][6]. Press coverage rounded the circumvention figure to $672,000 and described it as covering CMI removal rather than circumvention [1][2]. Commentators note that courts rarely award the statutory maximum on every work [3].

Suno’s training data and scraping allegations

The complaint draws heavily on Suno’s own prior court statements. In the RIAA-led litigation filed in June 2024, Suno acknowledged that its training data includes “essentially all music files of reasonable quality that are accessible on the open Internet” [1][2][6]. Eight Mile Style argues that its works, widely available on licensed streaming services, were almost certainly copied into Suno’s training sets [6].

The filing also cites a 2025 leak of Suno source code, reported by 404 Media, which allegedly shows the company used Bright Data proxy services to scrape millions of songs and lyrics from YouTube Music, Deezer and Genius. The complaint says the code reveals a YouTube Music workflow saving over two million artist records and a Genius workflow with nearly seven million successful song-page extractions [6]. It further alleges Suno used stream-ripping tools such as yt-dl and yt-dlp to circumvent YouTube’s “rolling cipher” encryption and download audiovisual content [6].

Output examples and guardrail bypasses

The complaint includes exhibits of Suno-generated tracks that it says reproduce Eminem’s lyrics verbatim or near-verbatim, including “Lose Yourself,” “The Real Slim Shady,” “Houdini” and “’Till I Collapse.” One track, “Slim shady x Rosefalls,” uses an AI-generated image of Eminem as cover art and vocals “clearly derived from Eminem’s actual voice” [1][2][6].

Suno blocks prompts that name specific artists. However, the lawsuit says those guardrails are easily circumvented. It cites a third-party service, HookGenius, which sells “Eminem-style” prompt packs — strings such as “aggressive rap, rapid-fire flow, dark humor, male rapper, horrorcore, intense beat, bass-heavy, menacing, controversial” — that produce Slim Shady-like output [1][2][6]. The complaint also references a Suno-affiliated creator who posted a tutorial on “how to get around” the artist-name restriction and earned a referral commission [6].

Suno’s V6 model, released September 2026, now “redirects” artist-name prompts “toward descriptive musical characteristics” that Suno attributes to that artist, which the complaint argues is an admission that the system was designed to model pre-existing works [6].

Suno’s response and legal context

A Suno spokesperson told the Detroit Free Press: “Suno exists to help people create new, original music, not to trade on anyone's name or likeness, and we prohibit any unauthorized use of an artist's work. To protect against this, we do not allow prompts for specific artists' names and songs and work with third party providers to screen uploaded audio files and lyrics for potential misuse. We are always working to strengthen our guardrails and we will continue to add new safeguards that protect artists and our users” [1]. In earlier cases, Suno has argued its training constitutes fair use under U.S. copyright law [2].

The suit arrives amid a growing docket. The RIAA sued Suno in June 2024 on behalf of major labels, including Universal Music Group, Eminem’s record company, which remains a plaintiff. Warner Music Group and BMG have since struck licensing deals with Suno [1][2][4]. In August 2026, a German court ruled against Suno in a case brought by collecting society GEMA, finding that Suno needed a license for training on GEMA’s works in the U.S. and granting an injunction and disclosure order [6]. Collecting societies in Denmark and Canada have filed similar suits [6].

On the same day, Elvis Presley Enterprises filed a separate lawsuit against Suno, invoking Tennessee’s ELVIS Act, which adds “voice” to the state’s personal rights law and allows claims against companies that build voice-cloning tools [5]. The same legal team represents both Eight Mile Style and the Presley group [3][5].

What’s at stake

The $41 million figure is a statutory ceiling demand for the copyright and circumvention claims, not a predicted award; the CMI claim adds a further $6.725 million. The guardrail argument — whether style descriptors that effectively target a specific artist constitute infringement — may prove more consequential than the damages number. The complaint also revives the metadata-stripping claim under DMCA Section 1202, alleging that Suno deliberately excluded headers and footers containing CMI during scraping [6].

Eminem himself is not a party to the suit; the plaintiff is the publishing entity [4]. Suno has not yet answered this complaint. The case will test whether training on “essentially all music files” without licenses survives fair-use scrutiny, and whether output that mimics a specific artist’s voice and lyrics via descriptive prompts crosses the line from style to substitution.
