Suno, the platform that lets users generate songs with AI, announced new measures to mark tracks created on its service, limit downloads, and update community guidelines to prevent imitation and misuse. The changes come while the company is facing multiple lawsuits and scrutiny over past data-handling practices.
Mikey Shulman, Suno’s co-founder and CEO, set out core principles in a blog post, saying the company wants to encourage original creation and provide tools that let more people make music using AI while reducing potential abuse.
Technical measures being deployed
- Suno said it will apply audio watermarking and fingerprinting to help stop tracks created on its platform from being misused or monetized improperly on other streaming services. The company did not specify whether it will adopt an existing system such as Google’s Synth ID or develop its own solution.
- The startup signed an agreement with lyrics provider Musixmatch to use its Sentinal system for copyright detection, according to the blog post.
- Suno also plans to introduce a new download policy intended to bar mass distribution of tracks to streaming platforms, but the company declined to provide further details on how that policy will work.
In his post, Shulman said: “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.” He added that ultimately artists and platforms should decide what to disclose, and Suno’s role is to offer transparency options that make industry collaboration easier.
Stricter community guidelines
Suno updated its community guidelines to explicitly ban “deceptive audio presented as real” and the use of a real person’s voice or likeness without permission, aiming to curb copycat content and unauthorised impersonations.
Legal and security context
The announcement comes amid several legal challenges. Suno is being sued by Universal Music Group (UMG) and Sony Music Group in a case coordinated by the Recording Industry Association of America (RIAA). A German court recently ruled in favor of the government‑mandated licensing agency GEMA, finding that Suno had violated copyright rules.
Separately, 404 Media reported that Suno experienced a data breach in November 2025 that revealed the company had scraped sources such as YouTube, Deezer, and Genius to train its models. Have I Been Pwned later stated that the breach affected 55 million users. Suno is also facing a class action in Massachusetts alleging the company prioritized profit over implementing adequate security measures.
Suno raised $400 million in a Series D funding round in June. The company says it will continue developing its technology and updating policies as it navigates legal pressures and community concerns.
