hit](https://nypost.com/2025/07/31/tech/can-you-tell-if-that-song-is-ai-generated/).\n\nLA-based rapper Fenix Flexin has been forced to deny allegations that his wildly popular new song “Rubberz” was generated using artificial intelligence — as internet sleuths and music industry figures pick apart everything from his vocals to the track’s production.\n\nThe song, released in June, has become a bona fide hit and was sitting at No. 66 on the Billboard Hot 100 on Wednesday morning.\n\nBut its rise has been [dogged by speculation](https://nypost.com/2025/07/10/entertainment/rock-band-with-more-than-1-million-spotify-listeners-reveals-its-entirely-ai-generated-down-to-the-musicians-themselves/) over whether Fenix actually made the song himself, with listeners pointing to the rapper’s dramatically different vocals, a surprise British accent and a sound far removed from his previous music, [according to Futurism](https://futurism.com/artificial-intelligence/rapper-denies-song-is-ai-generated).\n\nListeners certainly have their suspicions.\n\n“All yall not having any idea this ENTIRE song is all AI is hilarious,” one YouTube commenter wrote beneath the music video.\n\n“when yyou throw your lyrics into AI while asking it to sound like the smiths lol,” another joked.\n\nOthers branded it an “AI classic” and “AI Slop,” while one simply declared: “Definitely produced by AI.”\n\nSkeptics have also zeroed in on Fenix hitting higher notes than he has typically demonstrated in his music, while one YouTube clip appears to show the rapper awkwardly lip-syncing along to the track.\n\nThe bizarre controversy even prompted Fenix to directly address the rumors during an interview clip shared by music outlet Stereogum.\n\nWhen asked if there was anything he wanted to clear up about the song, Fenix immediately replied, “The AI sh-t?”\n\n“Nah, s—t is recorded like any other song,” he insisted.\n\nThe clip then cuts to Fenix performing “Rubberz,” where he appears to lose track of portions of his own song.\n\nStereogum cheekily captioned the post: “me when I lie.”\n\nLegendary producer Timbaland has come to Fenix’s defense, according to Futurism — although that did little to quiet the skeptics given the hitmaker’s own enthusiastic embrace of AI-generated music.\n\nProducer Medasin was among those questioning the song’s origins, [publishing a detailed breakdown](https://www.instagram.com/reel/Dbbf1vCBuGO/) last week laying out why he believes “Rubberz” was made using AI.\n\nMedasin claimed a file name visible in a snippet Fenix previously posted of the unfinished track contained the word “Sonauto” — the name of an AI music-generation platform that rebranded as Treblo just two days before “Rubberz” was released.\n\nFenix later tried to swat down the accusations by posting a video showing a Pro Tools project for “Rubberz,” seemingly offering the session as evidence that the track had been put together conventionally.\n\nBut critics, including Medasin, remained unconvinced, according to Futurism, which noted an AI-generated track could theoretically be separated into individual stems and imported into a project.\n\nFenix later deleted the video, according to the outlet.\n\nDespite all the online detective work, there has been no definitive proof that “Rubberz” was generated using AI — and Fenix has flatly denied that it was.\n\nFor now, listeners will have to decide for themselves.\n\n**Download The California Post App, follow us on social, and subscribe to our
