It is all but confirmed that “Rubberz,” the Billboard Hot 100-charting song by Los Angeles rapper Fenix Flexin, was generated using AI. Flexin claims to have produced the song manually, going so far as to show off production stems, but for our purposes, it’s worth noting that “Rubberz” would never have a chance to drill into your ear without San Francisco. In a statement to Gazetteer, Treblo co-founder Ryan Tremblay said that the track was likely entirely generated using this service. Flexin vehemently denies any use of AI, but given the evidence and the uncanny valley feel of “Rubberz,” it seems the rapper doth protest too much. In a January interview with the private equity firm Sixth Street, Shami sounded excited about generative AI burrowing its way into the music industry.
