In 2026, la diaria Radio invited Oneira to host Banda Sonora Selectores, a space where guests choose the music and talk between songs. Initially, she thought she'd be making four playlists, but they ended up as four essays with music inside them. Each program started from a concept and a stack of research into who made the songs and what they were answering to. She wrote every spoken block, then recorded and mastered the full hour herself.
