I’m Sinisa Reljic (Simba), a music producer and composer specializing in mainstream pop production, arrangement, mixing and mastering.
I work also with finished AI-generated songs, helping transform tracks into polished, release-ready pop productions.
I focus on modern pop structure, strong hooks, clean vocals, and radio-ready sound quality. My role is to refine, enhance, and mix AI-generated material so it feels cohesive, human, and competitive with today’s mainstream releases.
If you’re looking for a reliable pop producer to elevate your AI or traditional music project to a professional level, I’d be glad to collaborate.
