AI Music Platform Suno Introduces Watermarking and Download Limits Amid Copyright Lawsuits

AI music platform Suno has announced sweeping changes, including the integration of invisible, tamper-resistant audio watermarks and new download limits to curb the mass distribution of AI-generated tracks on streaming services. The policy overhaul, detailed by CEO Mikey Shulman, comes as the company fends off major copyright infringement lawsuits from Sony and Universal, a recent adverse ruling in Germany involving GEMA, and a class action lawsuit over a massive 55-million-user data breach.

Suno audio watermarking technology

• ▪Suno's planned watermarking system is designed to embed an invisible code directly into the audio waveform without degrading the listening experience

Download limits for users

• ▪Suno announced plans to implement a new download policy designed to limit the mass distribution of AI-generated songs on streaming platforms

Copyright lawsuits against Suno

• ▪Suno is fending off copyright infringement lawsuits in the United States filed by major record labels, including Sony Music Entertainment and Universal Music Group, coordinated by the RIAA
• ▪A German court in Munich ruled in late July 2026 that Suno violated copyright rules by training its systems on protected music represented by licensing agency GEMA
• ▪Suno faces a class action lawsuit in Massachusetts alleging it overlooked security measures, following a late 2025 data breach that reportedly exposed the personal information of 55 million users
