Summary
Fenix Flexin said his June single “Rubberz” was not AI-generated after the track climbed to No. 58 on the Billboard Hot 100 and drew widespread scrutiny.
Medasin and other critics pointed to a posted snippet with “Sonauto” in the file name — matching an AI music tool that rebranded to Treblo two days before the song’s release.
The Verge and songwriter Charlie Harding also cited audio artifacts they said resemble AI output, including brittle hi-hats, low-bitrate-sounding chorus vocals and abrupt reverb cutoffs.
A Pro Tools video Fenix shared as proof he made the song by hand failed to settle the dispute, with skeptics saying stems could have been split after generation; he later deleted the clip.
The dispute adds to broader music-industry anxiety over generative AI, with Timbaland’s defense of the track intensifying attention because of his public support for AI tools.
