AI Music War Escalates: Suno Hit With New Lawsuit Claiming Indie Duo Lost Nearly 80% of Licensing Revenue

The legal pressure surrounding AI music company Suno continues to intensify. Poseidon Wave Media — the entity behind ambient instrumental duo The American Dollar — has filed a new copyright infringement lawsuit against the AI music platform, alleging that Suno trained its technology using the group's catalog without permission and helped devastate a business model that took decades to build.

According to the complaint filed in the U.S. District Court for the Southern District of New York, Poseidon Wave Media claims Suno ingested 236 copyrighted sound recordings and compositions spanning 164 registrations. The lawsuit alleges the company copied and used those works to train its AI music generation systems without authorization.

The most striking allegation may be financial. The lawsuit claims licensing revenue connected to The American Dollar has dropped by nearly 80% since Suno publicly launched its AI platform. The filing argues there is a clear revenue decline tied directly to the rise of AI-generated music entering the market.

The American Dollar — formed by John Emanuele and Richard Cupolo — spent years building a reputation in instrumental, cinematic, and post-rock music circles. Their music has reportedly appeared in projects involving major companies and media organizations including Apple, Activision, PBS, Warner Bros., MLB Network, and television series such as CSI: Miami and 30 for 30.

The lawsuit claims Suno's technology became more than a competitor. It argues AI transformed into a direct market disruptor capable of generating music similar to the sounds independent artists spent years developing. According to the complaint, one member of the duo tested Suno by entering prompts instructing the system to create music sounding like specific American Dollar tracks. The filing claims generated results showed substantial similarities.

This case also arrives as Suno faces broader scrutiny from across the music industry. Major labels including Sony, Universal, and Warner previously pursued legal action against AI music platforms over allegations involving unauthorized use of copyrighted recordings in training systems. Those cases have increasingly become central to a larger debate over how artificial intelligence should interact with creative work.

At the center of the fight sits an increasingly uncomfortable question: when AI learns from music, where exactly does inspiration end and infringement begin?

For independent musicians especially, that answer may determine much more than technology policy.

It may determine whether entire careers remain economically viable in the AI era.

The allegations outlined in the complaint remain claims made by the plaintiffs. Suno has denied infringement allegations in prior litigation, and the company has not been found liable in this matter. All parties remain entitled to the legal process as the case proceeds.
