Producer's metadata analysis alleges Fenix Flexin's "Rubberz" is fully AI-generated

Producer Medasin posted a viral video breakdown alleging Fenix Flexin's "Rubberz" is fully AI-generated, citing "Sonauto" — the former name of AI tool Treblo — left in the song's embedded metadata. Metadata signatures persist through downstream mixing and mastering. Treblo's own detector and Pitchfork's independent test both flagged the track as "very likely Treblo"-created.
