Sure seems like Fenix Flexin used AI music generator Treblo

Treblo released an open-source AI Music Classifier designed to identify songs generated by its own platform, claiming a false positive rate under 1 in 10,000. The tool labeled Fenix Flexin’s “Rubberz” as very likely Treblo with high confidence, reinforcing earlier suspicions about the track’s origins.

The case shows how AI music platforms may increasingly become both creation tools and forensic authorities for identifying synthetic tracks. If reliable, provenance detection could reshape how artists, labels, and listeners handle disclosure, credibility, and backlash around AI-generated music.
