Suno, the AI music generation platform, announced new watermarking technology and download restrictions designed to prevent users from uploading AI-generated songs to streaming platforms and gaming the revenue system. The moves come as the company faces legal pressure from Universal Music Group, Sony Music Group, and other rights holders over copyright concerns.

What Is Suno Doing to Address Copyright and Spam Issues?

In a blog post, CEO and co-founder Mikey Shulman laid out the company's response to mounting legal challenges. Suno plans to implement audio watermarking and fingerprinting technology to mark tracks created on its platform, making it easier to identify AI-generated content across streaming services. The company also signed an agreement with lyrics provider Musixmatch to use its Sentinel system for copyright detection.

"These tools are designed to be durable and resistant to tampering, without affecting the listening experience. They are also not intended to pass judgment on whether a song is good, meaningful, or sufficiently human," said Mikey Shulman, CEO and co-founder of Suno.

The watermarking approach aligns with emerging industry standards, according to Shulman's statement. However, it remains unclear whether Suno will adopt an existing system like Google's Synth ID or develop its own proprietary solution.

How Is Suno Changing Its Download and Community Policies?

• Download Restrictions: Suno plans to implement a new download policy that will limit mass distribution on streaming platforms, though the company has not yet provided specific details about how the restrictions will work.
• Subscriber-Only Downloads: Last year, following a settlement with Warner Music Group, Suno announced that downloads would be limited to paying subscribers with monthly download caps, though full details remain pending.
• Updated Community Guidelines: The platform explicitly prohibits "deceptive audio presented as real" and "using a real person's voice or likeness without permission" to prevent users from creating misleading or unauthorized content.

These policy changes directly address one of the key points of contention: users uploading AI-generated songs to other streaming platforms and earning revenue from content that violates copyright or misrepresents its origin. The watermarking and fingerprinting tools are intended to make it easier for distribution platforms to identify and block such misuse.

Why Is Suno Under Legal Pressure?

Suno faces lawsuits on multiple fronts. The company is in a coordinated legal battle with Universal Music Group and Sony Music Group, with the Recording Industry Association of America (RIAA) coordinating the case. Additionally, a German court ruled in favor of GEMA, a government-mandated licensing agency, determining that Suno was breaking copyright rules.

The company also experienced a significant data breach in November 2025 that revealed it had scraped YouTube, Deezer, and Genius to train its models, affecting 55 million users. This breach led to a class action lawsuit in Massachusetts alleging that Suno prioritized profit over security measures.

Despite these challenges, Suno raised $400 million in a Series D funding round in June 2026, demonstrating continued investor confidence in the AI music generation market.

What Does Suno Say About Its Role in the AI Music Ecosystem?

Shulman emphasized that Suno believes transparency and respect for rights holders are essential. However, he also stressed that the company does not intend to "pass judgment" on whether individual pieces of art are valuable or sufficiently human-created. Instead, Suno argues that it is up to artists and platforms to decide whether they want to disclose the use of AI tools.

The company stated it plans to partner with "distribution platforms on combatting fraud and misuse," positioning its watermarking and detection tools as industry-wide solutions rather than Suno-specific measures. This collaborative approach reflects a broader shift in the AI music industry toward self-regulation and transparency as legal and public pressure mounts.

Suno's announcement signals that AI music generation platforms are moving beyond pure innovation toward accountability mechanisms. Whether these measures will satisfy regulators, courts, and rights holders remains to be seen as the company continues to defend itself in multiple jurisdictions.
