- Fenix Flexin (Shoreline Mafia member) saw his solo track 'Rubberz' reach #58 on the Billboard Hot 100, a dramatic stylistic shift from his trap roots to '80s UK synth pop with a Morrissey-esque vocal melody.
- Charlie Harding, co-host of the Switched on Pop podcast, identified audio artifacts including ghostly backing vocals ducking in and out, unnatural digital artifacting reminiscent of a 64kbps MP3, and a 'complete lack of flow' in the title line.
- Five AI music detectors gave the track only 20–30% probability of being AI-generated, but multiple AI image detectors flagged the single's cover art and a success-celebrating post at over 97% certainty.
- Fenix's live performances showed him unable to replicate the recorded vocal range or accent, awkwardly lip-syncing in early appearances, with the DJ briefly dropping the backing track to prove authenticity and failing.
- Fenix has attributed the live-versus-recorded gap to vocal processing and AutoTune, a claim disputed by Harding, YouTuber Curtiss King, and Anthony Fantano, who note AutoTune cleans errors but cannot extend vocal range or introduce an accent.
- Fenix posted clips of what he says are Pro Tools session files, but without sharing original recordings and project files publicly, analysts say the AI allegations are unlikely to be resolved.
Why it matters: If 'Rubberz' is AI-generated, it represents one of the first suspected AI slop tracks to crack the Billboard Hot 100's top 60 — and the case shows how thin the evidentiary tools still are, with music detectors returning only 20–30% confidence while supporting artwork hit 97%+ AI likelihood across image detectors.
