Round Hill Music LP et al. v. Suno, Inc. et al. is a federal copyright and DMCA action alleging that Suno used protected musical works to train its generative-music models and that Bright Data supplied scraping and proxy infrastructure used to obtain the works.[3][4]

Allegations

Round Hill alleges that it owns or controls rights in 14,364 musical compositions and 16,873 sound recordings and identifies 500 compositions as an initial bellwether set.[3] The complaint alleges that Suno copied works from licensed streaming and lyrics services for model training without authorization and used Bright Data tools or services to bypass access controls.[3]

The complaint further alleges that Suno's training and output processes reproduced protected works and that Suno and Bright Data removed copyright management information.[3] It names Bright Data on a contributory-infringement count and alleges that its scraping infrastructure materially enabled Suno's copying.[3]

Claims and Relief Sought

The complaint asserts direct infringement against Suno, contributory infringement against Bright Data, and DMCA claims against all defendants for alleged circumvention and removal or alteration of copyright management information.[3]

Round Hill seeks declaratory and injunctive relief, damages or profits, statutory damages, an accounting, and impoundment or destruction of unauthorized copies allegedly retained in datasets, repositories, model weights, and server infrastructure.[3] The complaint says Round Hill may amend the case to cover 10,000 or more works and alleges that claimed statutory damages could approach or exceed $1 billion.[3][4]

Significance

The action expressly seeks relief directed at model weights rather than only source files, presenting a potential remedy with consequences for deployed AI systems if Round Hill prevails.[3][5] It also places a data-scraping vendor in the case as an alleged contributor to the AI developer's infringement.[3]
