Fenix Flexin' New Single Sparks AI Slop Debate Over...

"Rubberz" sits at number 58 on the Billboard Hot 100 this week, a real chart position for a song a growing number of listeners suspect wasn't really written or sung by a human being. The track comes from Fenix Flexin, one half of the Los Angeles rap duo Shoreline Mafia, and it sounds nothing like the trap-inflected West Coast material that made his name. Instead, "Rubberz" borrows its melody and mood from 1980s UK synth pop, with Fenix adopting a fake British accent that lands somewhere between homage and impersonation of Morrissey.

That kind of stylistic jump isn't automatically suspicious. Artists change lanes all the time, and a rapper trying on a new sound doesn't prove AI involvement on its own.

What's harder to explain away is how the record actually sounds up close. Listeners and critics have pointed to specific production quirks, the kind that show up often in AI-generated tracks, as evidence something automated is at play. Fenix has pushed back on the accusations without offering much to settle the question either way. Charlie Harding, songwriter and co-host of the Switched on Pop podcast, laid out for The Verge exactly what those red flags sound like.
