In brief
Los Angeles rapper Fenix Flexin has indicated that AI was involved in creating “Rubberz,” an ’80s synth-pop-influenced track, while distinguishing that use from the song’s recording process. His comments came after producer Medasin linked the track to the AI tool Treblo, formerly Sonauto.
Fenix Flexin said he had not denied using AI and only learned about the app during mixing.
