Summary

Story summary

Rapper Fenix Flexin announced on Aug. 7, 2026 that he used the AI tool Treblo for “Rubberz.”
“Rubberz” reached No. 58 on the Billboard Hot 100, the first fully AI-generated track to chart.
Producer Medasin cited a “Sonauto.mp3” file—Sonauto being Treblo’s former name—as AI evidence.
Treblo’s detector marked the track “very likely” AI-generated, citing a false-positive rate under 1 in 10,000, and prompted major labels and the IFPI to draft international principles for AI-assisted chart entries.

History

Historical Context

Napster, launched June 1 1999 by Shawn Fanning and Sean Parker, grew to 26.4 million users by February 2001 and faced RIAA lawsuits that produced a March 5 2001 injunction. The case set a precedent for industry anti-piracy rules, now reflected in the IFPI’s 2024 draft principles for AI-generated music. That legacy pushes chart compilers to embed detection tools for tracks like Fenix Flexin’s AI single “Rubberz.”
