Suno adds watermarks to AI music, seeks legal ground amid lawsuits

Suno's turn toward watermarks and download restrictions comes at a moment of acute legal pressure. The company is defending itself across multiple jurisdictions: Universal and Sony are suing it in the US for copyright infringement, a German court has already ruled against it on music licensing violations, and a Massachusetts case targets the company over its handling of the late 2025 hack that exposed the scraping of training data and user information. Each of these cases carries the potential for substantial fines. The hack itself—and Suno's failure to disclose it—has been particularly damaging to the company's credibility, showing that the platform's training practices were opaque and possibly in violation of the terms of service of the platforms whose content was used.

By introducing watermarks and enforcing download caps, Suno is attempting to signal a shift in its business model and purpose. The company's framing emphasizes that its tools support the artistic process rather than enabling spam or industrial-scale content production, a distinction that may matter in court. Suno also points to existing safeguards—prohibitions on naming specific artists and partnerships with rights-management platforms like Musixmatch—as evidence of good-faith effort to prevent misuse. However, the timing and the legal necessity behind these moves suggest they are reactive measures taken under duress, not proactive safety choices.
