Rubberz

“Rubberz” is, technically, a landmark: the first fully AI-generated song to chart on the Billboard Hot 100, peaking at No. 58 this summer after months of TikTok momentum. It is also, on its own terms, a fine but unremarkable synth-pop single — a warped, faux-Morrissey croon riding a clean dance-pop chassis, reverbed to the point where it’s genuinely hard to tell where the Auto-Tune ends and the software begins. That confusion turns out to be the entire plot.

Fenix Flexin, a Shoreline Mafia veteran with a track record in laid-back West Coast rap, didn’t announce “Rubberz” as an AI experiment. He let it climb the charts as a regular song, credited to himself and producer Purps on the Beat, generated in part through the AI platform Treblo. When producer Medasin published a stem-by-stem breakdown alleging the vocal and arrangement were AI output almost start to finish, Flexin’s first move wasn’t clarification — it was a screenshotted Pro Tools session, offered as proof of a human session that a separated set of stems immediately undercut. The post came down. The denials kept going for weeks. The admission, when it finally arrived in August, was framed as “using new technology as a tool,” which is a fair description of a hammer and a much stranger one for a singing voice.

None of that would matter if the song didn’t work, and mostly it does — the hook is durable, the arrangement is disciplined, and the alien quality of the vocal is genuinely more interesting than a conventional take would have been. But knowing what we now know, the song’s biggest formal choice — a voice pitched to sound like it’s imitating a very specific, very human vocal mannerism — reads less like an artistic decision and more like camouflage. The record isn’t strange because it’s experimental. It’s strange because it spent months trying very hard not to be noticed as strange at all.

That’s the real Wack Wednesday material here: not the AI, which barely registers as a novelty anymore, but the reflex to hide it once the audience showed up. 5.4/10 — a competently built single that would have scored a point or two higher as an honest AI record than it does as a caught one. For a song that came clean the moment it stopped being profitable to lie, see our companion review of IngaRose’s “Celebrate Me,” which never bothered pretending in the first place.
