Winamp's Jamendo Sues Suno for $20M Over 55,600-Track AI Training Dataset

The Lawsuit: Claims Against Suno

Jamendo alleges that Suno used a dataset of approximately 55,600 tracks from Jamendo's catalog to train its AI music-generation models without authorization . According to the complaint, the tracks were used in three ways that each constitute infringement: (1) without a license; (2) without payment to Jamendo or the artists; and (3) without Jamendo's consent as the rights holder .

The lawsuit further asserts that Suno's use directly competes with Jamendo's own licensed AI music offerings. Jamendo operates a catalog of over 800,000 tracks for personal use and an additional 300,000 songs for commercial applications . The company had publicly called out both Nvidia and Suno for unauthorized use as early as January 2026, and reaffirmed its intent to pursue legal action in February 2026 , meaning the lawsuit followed months of pre-litigation demand.

Potential Damages

Jamendo is seeking statutory damages of up to $150,000 per infringed work under U.S. copyright law, plus attorneys' fees and injunctive relief . Given the 55,600-track dataset at issue, the maximum statutory damages could theoretically reach into the billions, though courts typically award far lower amounts. Multiple news reports peg the lawsuit's stated damages claim at $20 million (approximately €17.8 million) .

Suno, the defendant, was recently valued at approximately $5.4 billion following its latest funding round, according to Winamp Group's regulatory filing on Euronext .

Jamendo's Broader Pattern of AI Copyright Enforcement

Jamendo has pursued a coordinated, two-front legal strategy in the summer of 2026:

• June 23, 2026 — Sued Nvidia in California federal court, alleging Nvidia used Jamendo's music catalog to train its Fugatto and Audio Flamingo AI audio models without permission .
• June 29, 2026 — Sued Suno in Massachusetts federal court over the 55,600-track dataset .

This represents a deliberate dual-target strategy against both the AI model developer (Suno) and the chipmaker whose hardware powers AI training (Nvidia). Jamendo discovered the alleged infringement in 2024 when its community alerted the company to online articles suggesting Nvidia and Suno had incorporated Jamendo's licensed music into their AI training datasets . After attempting to resolve the matter amicably—including sending invoices to Nvidia in 2025 and filing a separate lawsuit in Belgium—Jamendo escalated to U.S. federal court . Jamendo stated that while Nvidia engaged in some discussions, Suno "failed to respond entirely, ignoring Jamendo's repeated efforts to establish communication" .

Jamendo's Winamp parent company formally announced both suits via press release and regulatory filing on Euronext on June 30, 2026 .

How Jamendo's Lawsuit Differs from the Major Label Fight

The suits put Jamendo alongside the major record labels — Universal Music Group, Sony Music, and Warner Music Group — who have been litigating against Suno since June 2024 in the RIAA-led lawsuit . However, while the majors have largely pursued settlements (Warner Music settled with Suno in November 2025; Universal settled with Udio in October 2025), Jamendo is pursuing independent litigation as a rights holder for independent and licensed music .

As of mid-2026, Sony Music Entertainment continued its active litigation against both Suno and Udio, while Universal Music Group continued its case against Suno specifically . Jamendo's independent action means that even if the major labels reach a comprehensive resolution, Suno still faces separate copyright claims from an organized rights holder with a specific, documented catalog of 55,600 tracks.

The broader AI music copyright landscape in 2026 is increasingly fragmented: major labels, independent artists (via class actions), and independent licensing platforms like Jamendo are each pursuing separate legal theories and remedies against the same AI companies .
