Jason Isbell and David Lowery are suing Suno in a class action suit. Importantly, they’re hitting Mikey Shulman’s company with identity claims – not copyright.
Developing story first seen 2 hours ago
The lawsuit filing against AI music company Suno includes new detail beyond the initial reports: it cites Suno's own public denial that it enables such imitation, then directly disputes it, alleging the company's stated protections are ineffective. Suno had said it does not use artist names as training metadata and has "detection filters" blocking prompts naming specific artists, but the complaint calls this claim false and says users can bypass the filter simply by inserting spaces between the letters of a name, with tutorials on doing so allegedly published by Suno's own paid affiliate marketers.
The 84-page suit, filed on 31 August in Boston federal court by Jason Isbell, David Lowery, Guy Forsyth and Eduardo Calle, spans 17 legal counts but does not specify a damages figure, though it states the total claims across the proposed class exceed $5 million, the threshold required to bring the case in federal court. It provides further examples of the alleged behaviour, including prompts for "Camper Van Beethoven" generating a track described as "quirky late-1980s alternative rock," and similar outputs for Forsyth and Calle, alongside roughly 20 other artists such as Buddy Guy, Tom Waits and Carly Simon, with lawyers saying they hold dozens more examples on file.

Suno is an AI tool that lets anyone type a text prompt and get an original song generated, complete with vocals and instrumentation in the style requested. It has become popular for producing music that mimics the sound of well-known artists, raising questions about how it was trained and what safeguards, if any, stop people from generating songs designed to sound like a specific musician.
Jason Isbell and David Lowery are musicians and songwriters, and their new lawsuit is a proposed class action brought on behalf of a wider group of artists. Suno is run by chief executive Mikey Shulman. The case centres on claims about artists' identities rather than copyright, meaning the dispute is over whether Suno lets users generate music designed to sound like a particular artist without permission, rather than over the copying of specific recordings or compositions.
This matters because it is one of a growing number of legal fights testing how far AI companies can go in offering tools that imitate real performers' voices and styles, and how existing law applies to a technology that did not exist when many relevant rules were written. The outcome could influence how AI music services operate and what protections artists have over their identity in this new space.
Both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Advocates for the musicians argue that an artist's voice, name and stylistic identity are core to their livelihood and reputation, and that deliberately enabling fans to generate soundalike tracks by naming an artist exploits decades of built-up goodwill without consent or compensation. They contend that if Suno's own safeguards are as easily circumvented as the complaint describes, and if affiliate marketers were showing users how to do it, the company cannot credibly claim its stated protections were meaningful, making this less a novel copyright dispute than a straightforward case of unauthorised use of someone's identity for commercial gain.
The case against
Defenders of Suno and similar AI music tools argue that generating a track "in the style of" an artist, without reproducing their actual recordings or lyrics, is a longstanding creative practice akin to homage, parody or genre emulation, and that stylistic influence itself should not be monopolised by any one performer. They would emphasise that Suno states it does not use artist names as training metadata and has built filters specifically to deter direct impersonation, that isolated workarounds found by determined users do not necessarily reflect the company's intent or design, and that innovation in generative tools benefits musicians and listeners broadly, so liability should hinge on demonstrable harm and intent rather than the mere possibility of misuse by a subset of users.
