AI Music App Flags Song of the Summer as Likely AI-Generated
AI music app flags Fenix Flexin’s hit “Rubberz” as likely AI-generated, sparking debate over authenticity.

Fenix Flexin’s hit song “Rubberz” has ignited a heated debate among hip-hop fans, with some claiming it was entirely or partially generated by artificial intelligence. The controversy reached a peak this weekend after an independent music producer accused the rapper of using a lesser-known generative AI music app called Treblo to create the track. The app’s creators have since released a detector that flags “Rubberz” as “very likely Treblo,” adding fuel to the fire. The song, which currently sits at No. 58 on the Billboard Hot 100, has become a focal point in the growing conversation about AI’s role in music creation.
AI Music App Flags Song of the Summer
The controversy surrounding “Rubberz” began when a music producer named Medasin posted a video claiming he had uncovered how Fenix Flexin used Treblo to create the track. Medasin demonstrated how he could generate a song with Treblo that closely mirrored “Rubberz,” including similar lyrical structures and thematic elements. His findings sparked widespread discussion, with many fans and industry insiders questioning the authenticity of the hit. The app’s creators, Treblo, have since released a detector that identifies songs made with their tool, and “Rubberz” was flagged as “very likely Treblo.”
Medasin’s video was the first to capture attention, and it quickly became the center of a growing debate. The app’s detector, which has a false positive rate of under one in 10,000, has been used to flag both “Rubberz” and a track by Fenix’s labelmate, Tyga, as likely AI-generated. This has intensified the discussion over whether AI should be used in music and how it should be disclosed to listeners.
Generative AI in Music Sparks Concern
The rise of generative AI in music has raised concerns about the authenticity of content and the potential for misinformation. Treblo, a lesser-known AI music app, has gained attention for its ability to create songs that closely resemble human-made tracks. The app’s open-source code allows anyone to inspect and test its functionality, adding credibility to the claims. While some argue that AI can be a valuable tool for creativity, others believe it undermines the human experience in music. It is unethical to me on a very spiritual level, says Medasin, who has been vocal about the issue. He emphasizes that listeners should know what they are hearing, and that transparency is essential in an era where AI-generated content is becoming increasingly common. The debate has also sparked broader conversations about the need for regulation and labeling of AI-generated content, with some lawmakers suggesting that platforms should be required to visibly label such content.
Fenix Flexin and his producer, Purps on the Beat, have denied using AI at every turn. Fenix has claimed he “freestyled” the lyrics and used only auto-tune reverb, while Purps has not commented on the allegations. However, the release of Treblo’s detector has made it difficult to ignore the possibility that AI played a role in the creation of “Rubberz.” The case of “Rubberz” highlights the growing tension between innovation and transparency, and whether the public will accept AI-generated music as a legitimate part of the industry.
