声だけで恋した

"声だけで恋した" ("I fell in love with just a voice") is a J-pop single by SeNA, the AI diva project run by the producer BLUE, released in August 2026. The project describes it as a love story that starts from a voice, written around an easy-to-remember melody and a chorus hook meant to land in short social videos. In a personal essay, BLUE says it was one of the first songs to come out of trying the AI music service Suno in mid-January 2026: male-vocal attempts did not match what BLUE had in mind, but female-vocal songs did, and this was among the early ones, made before the SeNA character existed. It was later released through DistroKid as part of SeNA's first wave of singles.
