The Raza Turned Fenix Flexin's AI Hit "Rubberz" Into Corridos and Banda Anthems

Leave it to the raza to take somebody else's song and run off with it. The track in question is Rubberz by Fenix Flexin, a synthy, British-accented pop song that blew up over the summer and then got a second life once regional Mexican fans got their hands on it. Creators have been flipping it into corridos, banda versions, and full-on marching-band anthems, and for a lot of listeners, those fan-made takes hit even harder than the original. It is a familiar pattern, the culture absorbing a viral moment and remixing it into something that feels like home.

Part of what makes this so funny is the backstory of the song itself. Rubberz was confirmed to be AI-generated, built with a tool called Treblo, formerly known as Sonauto. Fenix Flexin initially brushed off the accusations before eventually admitting AI was used, after a producer publicly broke down the evidence. So the raza did not just remix a hit, they took an artificial intelligence experiment and ran it through the most human filter imaginable: an accordion, a tuba, and a whole lot of attitude. There is something poetic about a computer-made song only truly coming alive once real musicians got involved.

The regional Mexican wave reportedly kicked off through Israel De San Antonio, a rising corrido artist who helped push the first version into the genre, and from there it snowballed. Once one convincing corrido edit lands, everyone wants to try their spin, and the versions multiply overnight. Fans have even joked that some of these creators know the lyrics better than Fenix does, poking fun at how he sings certain lines. When your fan covers are more confident than your own performance, that is a sign the song has fully left your hands and become the internet's property.

It also lands at a moment when AI in music is impossible to ignore. The streaming service Deezer reported in 2025 that roughly 18 percent of the tracks uploaded to its platform each day were fully AI-generated, a staggering number that shows how normal this technology has quietly become. Rubberz is just the most viral face of that shift, and the raza reworking it into corridos is almost a statement in itself, a reminder that no matter how the song was made, culture decides what it becomes.

There is also a light irony worth appreciating. The original song leans on a fake British accent and machine-made polish, while the corrido and banda versions lean on regional instruments and traditions that go back generations. The newest technology in music got adopted by one of its most rooted communities, and the result is a mash-up of the very old and the very new. The bigger takeaway is a fun one. Whether a track is made by a superstar, a bedroom producer, or a piece of software, it still has to survive contact with the people, and the regional Mexican community has a long history of adopting outside sounds and making them unmistakably its own. Rubberz got the corrido treatment, the banda treatment, and the marching-anthem treatment, and honestly it is thriving.
