Treblo Confirms 'Rubberz' as First AI‑Generated Billboard Hot 100 Hit

Rapper Fenix Flexin's synth‑pop track "Rubberz" reached number 58 on the Billboard Hot 100 and amassed more than 7.5 million YouTube views. After months of speculation, the generative‑AI music app Treblo (formerly Sonauto) flagged the song as "very likely" created with its model and released a detection tool that it says has a false‑positive rate below 1 in 10,000. Treblo co‑founder Ryan Tremblay publicly acknowledged the AI involvement, effectively confirming the track as the first AI‑generated entry on the Hot 100 chart.

The controversy intensified when producer Medasin posted a detailed analysis showing how the song could be reproduced using Treblo and highlighted a file named "Sonauto" among the audio assets. Fenix Flexin briefly posted Pro Tools stems as proof of human creation but later removed them. The episode has sparked renewed debate over disclosure requirements for AI‑generated music and the broader impact of generative tools on the recording industry.
