Sunomarket fixes the three things that go wrong with Suno prompts: the model overrides what you wrote, the vocal drifts between sections, and artist names get refused. Instead of a blank box, you start from 1,960 style recipes or 1,003 artist recipes that describe a sound in descriptors rather than a name. The constructor validates as you build, rewrites negatives into positives, and outputs a Style field, an exclude list, a lyrics scaffold and a vocal block.
