AI music company Suno has filed its first response to the proposed class action brought by Jason Isbell, David Lowery, Guy Forsyth and Eduardo Calle, asking a federal court to dismiss the case. The musicians’ lawsuit, filed in August, says the service violates state publicity laws by enabling users to create music that draws on performers’ identities. Suno’s answer is direct: using an artist’s name as a reference point for musical style is a familiar form of creative communication, not an unlawful appropriation.
The dispute is important because it is not principally framed as a conventional copyright fight. The plaintiffs are pursuing a claim centered on identity: the idea that an artist has legal interests in the commercial use of attributes associated with them, even in circumstances where catalog licensing, training-data questions, or other copyright matters may be treated separately. Suno argues that the theory goes too far by trying to turn a broadly described artistic style into a protected form of property.
What Suno is asking the court to do
A motion to dismiss is an early procedural request. It does not decide whether every allegation is factually true after a trial. Instead, the defendant argues that, even taking the complaint’s core allegations as the court must at this stage, the claims do not establish a legally valid basis for relief. Suno is asking the court to end this particular case before it proceeds further.
Suno’s filing compares an AI-music prompt to ordinary language used during human music production. Musicians and producers often use a performer’s name as convenient shorthand when discussing a desired genre, mood, arrangement, vocal approach, or overall “vibe.” In Suno’s view, saying that a new piece should have more of a Jason Isbell-like feel is not fundamentally different from a user entering a similarly styled description into software.
“When people describe styles of music, they often use artists’ names as shorthand for the genre they perform in,” Suno attorney Andrew Gass wrote in the filing.
The company argues that the plaintiffs’ position would condemn that commonplace shorthand. It also maintains that the First Amendment protects this kind of reference to style. Suno’s argument is not that a performer’s name can never matter legally; rather, its position is that a lawful reference to artistic style cannot, by itself, become a state-law publicity violation.
The plaintiffs’ identity-focused theory
Isbell, Lowery, Forsyth and Calle allege that Suno exploits artists’ identities when users request tracks similar to particular performers’ work. They are seeking to proceed as a class action, which would allow the named plaintiffs to represent a broader group if the court grants class certification later in the case. At this point, the filing is a proposed class action, not a certified one.
The complaint’s focus on identity distinguishes it from other legal disputes involving Suno that have focused on copyright and that have led to lawsuits and settlements. The plaintiffs’ theory is that an artist’s identity interest can remain significant even if other questions surrounding a catalog are resolved, or if a musician permits training on their recordings.

That distinction matters. Copyright generally concerns protected original works, such as recordings or compositions. A right of publicity is a state-law concept that can concern the commercial exploitation of a person’s identity. The supplied allegations and Suno’s response present a conflict at the boundary between those concepts: is a prompt that invokes a recognizable creative persona merely a description of a style, or can it improperly use an individual’s identity?
Suno says Congress deliberately did not give artistic style intellectual-property protection, leaving later creators free to build on genres and prior creative work. Its filing argues that the plaintiffs’ approach would effectively create a parallel, state-level intellectual-property right over style that conflicts with the federal framework.
Why prompts and guardrails are central to the case
The musicians allege that Suno retains “voiceprints” associated with artists and that users can evade safeguards designed to limit direct artist-name prompts. Their complaint describes several purported ways around those guardrails: asking for a performer’s tone and phrasing, using a real name rather than a stage name, or spacing out the letters in a name.
“Voiceprints” in this dispute is the plaintiffs’ term for the alleged artist-linked characteristics they say users can access through prompting. The supplied filings do not establish, at this stage, what technical mechanism exists inside the system or whether the plaintiffs’ allegations will ultimately be proven. That distinction is essential. A complaint sets out accusations; Suno has denied the allegations and contests the legal premise behind them.
The practical question is therefore larger than whether a prompt includes a famous name verbatim. If a system blocks one exact phrase but users can reach a comparable result with adjacent descriptions, aliases, or altered spelling, a court could be asked to consider whether the underlying protection has meaningful effect. Suno instead argues that the act of using names as stylistic references is lawful in the first place, provided it does not infringe copyright or create confusion about who actually performed the track.
Style, imitation and consumer confusion are not identical
Suno’s filing draws an important line between an artist’s style and a claim that music is actually performed by that artist. In its argument, a producer may pursue an Isbell-like musical direction without implying that Isbell made the recording. The company says this does not create a likelihood of confusion over performer identity.
That framing makes consumer confusion a useful concept to watch. A style reference can be one thing; a claim, label, or presentation likely to make listeners believe a specific musician performed or endorsed a work is another. The supplied material does not say that this case has resolved where that line sits. Rather, Suno uses the absence of alleged performer confusion in its analogy to argue that the plaintiffs have not shown an unlawful use of identity.
The plaintiffs, by contrast, contend that the service’s outputs and prompting pathways can tap into qualities that remain inseparable from a musician’s identity. Their claim challenges the assumption that calling something a “style” neutralizes the implications of recreating a highly recognizable creative signature at scale.
What this could mean for creators and AI-music users
For musicians, the case raises a practical concern about the difference between influence and substitution. Musical influence has long been part of creative culture, and Suno emphasizes that artists regularly communicate through comparisons to predecessors and peers. Yet generative systems can potentially make stylistic emulation fast, repeatable, and widely accessible. The litigation is testing whether state publicity laws offer a remedy when artists believe that scale turns familiar imitation into identity exploitation.
For users of AI creative tools, the immediate lesson is not that a particular prompt is definitively lawful or unlawful. No ruling described here has made that determination. The more useful takeaway is that prompts are becoming legally consequential product behavior: the wording a tool accepts, the workarounds users attempt, and the degree to which an output is presented as belonging to a real person may all become relevant in disputes.
Creative software is also expanding in ways that make questions of user control and authorship increasingly visible. For a separate example of music-making tools moving toward more hands-on workflows, see OFFBEAT’s MIDI-control update. That broader software context does not decide Suno’s case, but it helps explain why the rules around creative direction, imitation, and attribution are drawing more attention.
What happens next
The court must first decide whether Suno’s arguments justify dismissal. The filing is not a finding that the musicians’ allegations are untrue, and the lawsuit itself is not a finding that Suno has violated any law. An attorney for the plaintiffs did not provide an immediate response to the dismissal request.
Whatever the eventual outcome, the dispute puts a narrow but consequential proposition before the court: whether an AI system’s acceptance of artist-based stylistic prompts should be treated like the longstanding human practice of referencing musical influences, as Suno says, or as an actionable use of musicians’ identities, as the plaintiffs allege. The answer could affect how generative-music services design prompt rules and how artists seek control over the most recognizable qualities of their work.
