Fenix Flexin Responds To Viral Breakdown Claiming “Rubberz” Is “Fully” AI-Generated
Shoreline Mafia rapper Fenix Flexin has responded to producer Medasin’s viral claim that his hit “Rubberz” was made entirely with AI, amid weeks of speculation over the track’s origins. The dispute matters because it highlights growing concerns about transparency in AI-assisted music production, particularly when artists may present generated material as conventionally recorded work.
Medasin alleged that Fenix Flexin and credited producer Purp On The Beat used Treblo, previously called Sonauto AI, citing a pre-release filename and demonstrations of similar output from the software. Fenix posted alleged stems and project evidence, but Medasin said these appeared to be AI output split into vocals, instruments, bass and drums, with real vocal layers added; Fenix later deleted the post. Purp On The Beat has not admitted AI generation, though he has argued that AI can be used as a creative tool.
In short
- Medasin says “Rubberz” was fully generated using AI software.
- Fenix Flexin posted evidence, then deleted it.
- The dispute centres on transparency around AI-made music.
Steelman: both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
If “Rubberz” was substantially generated by AI and presented without clear disclosure, listeners and collaborators could reasonably expect transparency, especially when conventional authorship and production credits shape how a song is understood. Medasin’s cited filename and comparison demonstrations may warrant scrutiny, while the disputed stems do not by themselves settle how the track was made.
The case against
The allegations remain contested, and a suggestive filename or resemblance to software output does not establish that the song was fully AI-generated. AI tools can be part of a producer’s creative process, and Fenix’s project evidence may support a different account; without clearer verification, it is reasonable to resist treating the claim as proven.
Explained simply
Shoreline Mafia are a rap group, and Fenix Flexin is one of their members. “Rubberz” is a song credited to Fenix and producer Purp On The Beat, while Medasin is another producer who has made claims about how it was created.
AI music tools can generate sounds or songs from prompts, and producers may also use them alongside recorded vocals or instruments. The dispute raises questions about how much AI was involved in “Rubberz” and what artists should tell listeners about the tools used to make a track.
