A Rapper’s Viral ’80s Song Appears to Be AI—and He Is Barely Denying It

AI music has produced another deliciously messy authenticity debate.
Los Angeles rapper Fenix Flexin attracted attention with “Rubberz,” an ’80s synth-pop-styled song that sounded dramatically different from his familiar musical identity.
Producer Medasin publicly argued that the track had been created using AI platform Treblo, formerly known as Sonauto. Treblo subsequently released its own detector indicating that the song was AI-created through its system. Fenix Flexin’s comments have been interpreted as effectively acknowledging AI involvement rather than firmly denying it. �

Why People Care
AI involvement does not automatically make a song bad.
The issue is disclosure.
Listeners increasingly want to know:
Who wrote it?
Who sang it?
Was the voice synthetic?
Was the instrumental generated?
How much did the named artist actually create?
The music industry previously tolerated enormous amounts of technological assistance—from Auto-Tune to samples and digital instruments—because the human creative chain remained reasonably understandable.
Generative AI makes authorship much harder to see.
The New Celebrity Problem
A famous artist has something an anonymous AI generator does not:
distribution and reputation.
If established musicians release AI-generated tracks under their names without clear disclosure, the audience may attribute machine-generated performance to the human brand.
That creates a fundamentally different relationship from an artist openly saying:
“I created this experimental track with AI.”
Mary Chuks’ Perspective
AI-assisted music does not frighten me.
Hidden AI authorship is the problem.
If the human directs the concept, writes, selects, edits and owns the creative judgement, say so.
If the machine created most of it, say that too.
The audience can decide what it values.
Transparency does not destroy creativity.
It protects trust.
Conclusion
“Rubberz” shows why the next music-industry standard will not simply ask:
Was AI used?
It will ask:
What exactly did the human do? �
