Jason Isbell Files Class Action Lawsuit Claiming Suno Coded AI to ‘Extract Musicians’ Identities’

Jason Isbell is leading a new class action lawsuit that accuses Suno of designing its AI music generator to evoke artists’ identifying characteristics.

The legal complaint, filed on Monday (Aug.

31) and obtained by Billboard , accuses Suno of violating artists’ so-called rights of publicity by encoding their entire musical personas as tokens in its AI model.

According to the lawsuit, this allows Suno users to generate songs, descriptions and artwork that “can conjure up a beloved musician’s identity” by prompting the model with a musician’s name.

“From a name prompt alone, a user receives a multi-modal experience evoking that named musician.

This includes access to a generated song like one the named musician might create, a description of the musician’s attributes and a related image.

This is true for countless other musicians.” As an example, the complaint says that typing Isbell’s name into Suno “produced an Americana song called ‘Paper Bell,’ imitating Isbell’s characteristic clear male vocals and country twang.” Isbell, who has previously made known his distaste for Suno, is leading the case alongside Camper Van Beethoven frontman and longtime artist rights advocate David Lowery , as well as blues singer Guy Forsyth and jazz saxophonist Ed Calle .

The group hopes to eventually represent a class of all the musicians whose names have been accepted as Suno prompts.

Suno has publicly stated that its goal is to “help people create something new, not imitate someone else’s work.” To this end, the AI company says it employs filters that block users from prompting the model with specific artist names.

For example, it says that typing in “m i c h a e l j a c k s o n” into Suno produced a pop song called “‘Glovebox Moonwalk,” complete with an image of Michael Jackson ’s signature white glove.
