Fenix Flexin's 'Rubberz' AI-Generation Claims Spark Online Debate

Rapper Fenix Flexin's viral summer track "Rubberz" has become the focus of a heated online dispute over whether the song was created with artificial‑intelligence tools. Producer Medasin posted a video alleging that Flexin and credited producer Purp On The Beat used the AI music software Treblo (formerly Sonauto) to generate the track, pointing to a pre‑release file name and demonstrating similar lyrics produced by the program.

In response, Flexin shared the song's individual stems, asserting that the track was assembled through conventional recording techniques. He later removed the post, while Medasin continued to argue that the stems were derived from Treblo output and that Flexin had layered his own vocals over the AI‑generated material. No definitive confirmation has emerged, leaving the debate unresolved.
