"Brain on Prime" turned Prime Video into a creator-powered platform fueled by the science of sonic storytelling. It all started with a custom brand track—written in three languages to cover seven culturally distinct international markets, and crafted using the psychology of earworms: looping rhythms, cultural hooks, and emotional resonance designed to stick. We kicked off with a music video starring top creators from around the world, performing on sets lifted from Prime Video’s most iconic titles. It brought our creative prompt to life: “Share your brain on Prime.” Not a directive, but a creative spark—handing talent the space to interpret what Prime meant to them. From there, the campaign became a wave. Across TikTok, Reels, and Instagram, 75+ creators built original content rooted in genre fandoms, local humor, and personal identity. In Colombia, it became a dramatic call to action. In Brazil, a haunted detective story. In Mexico, a Magic Mike parody went rogue. Each piece was wildly different—but all tied together by the Prime Video titles that lived rent-free in their heads. Rather than push traditional branded content, we reverse-engineered how people consume and share entertainment online—fusing music, platform behavior, and creator POV. This was storytelling from the inside out, driven by cultural fluency and creative trust.
