Suno Tells Court There Is 'Nothing Unlawful' About Artist-Name Prompts

By Tom Whitfield

Suno has asked a federal court to dismiss Jason Isbell's class-action lawsuit, arguing in a filing on Tuesday that there is "nothing unlawful" about users invoking artist names to describe a genre of music.

The AI music generator's first response to the case attacks its central premise. Isbell, the Americana singer-songwriter, joined musicians David Lowery, Guy Forsyth and Eduardo Calle in the suit, filed in August. Their claim targets state publicity laws, not copyright — a deliberate distinction from the wave of copyright litigation that has already produced settlements with Suno.

What does Suno actually argue?

Suno's attorney, Andrew Gass, compared prompting the service to a routine studio exchange between musicians and producers.

"When people describe styles of music, they often use artists' names as shorthand for the genre they perform in," Gass wrote. "The Complaint in this case turns on the premise that the law somehow condemns that universal practice."

Gass pressed the point further, invoking federal copyright doctrine. "Congress made the considered policy choice not to confer intellectual property protection on an artistic style, precisely to allow subsequent creators to build on the prior works of a genre," he wrote. "The theory of this Complaint would create a shadow state law IP regime sitting on top of and fundamentally conflicting with the federal regime that has been in place for more than two centuries."

Suno also claims First Amendment protection for artist-name prompts.

"No state confers a right of publicity that prohibits a musician in a studio from saying to their producer, 'let's go for something here with more of a Jason Isbell vibe,' and actually achieving that result without infringing any copyright or creating a likelihood of confusion over the identity of the performer," the filing reads. "And what Suno does, by Plaintiffs' own account, is no different."

An attorney for the plaintiffs did not respond to a request for comment.

What are the 'voiceprint' claims?

The plaintiffs allege Suno retains "voiceprints" of artists and that users can bypass the company's guardrails to reach them. Their filing details specific workarounds:

• Prompts that avoid the artist's name but ask for their "tone and phrasing"
• Real names used in place of stage names, as with the rapper Common
• Spacing out letters, such as "t a y l o r s w i f t" instead of Taylor Swift

Suno denies those claims outright.

Why this case is different

The Isbell group's suit stands apart from other litigation against Suno by focusing on identity rather than copyright. The plaintiffs argue that a musician's identity remains theirs regardless of any settlement deal or whether an artist opts in to letting Suno train on their catalogues.

That is the practical question at stake: what does this change for artists who have settled, or licensed, their catalogues to AI firms? Under the plaintiffs' theory, identity rights survive those deals. Under Suno's theory, invoking a style is not an identity right at all.

Skeptics will note what the filing does not address in detail: whether the alleged "voiceprints" exist, and whether spaced-letter prompts actually reproduce a specific performer's sound. Suno denies the allegations, but the dismissal motion leans on legal framing rather than a technical rebuttal.

The judge's ruling on the motion will determine whether identity-based claims against AI music tools get their first full airing in court — or whether artist-style prompts remain, as Suno insists, ordinary speech.
