A free generation service becomes more valuable when the output helps more than one person. If every public track disappears after one download, the site remains a tool. If useful generations become searchable public pages, the site becomes a library.
The BGMFREE promise is simple: free generated tracks belong in the public library and can be used freely as background music. That promise should be visible near the create button, on each track card, and inside the license modal. Users should not have to hunt for it.
The other side of the promise is anti-monopoly. A public track should not be registered into Content ID by a user who did not create it exclusively. It should not be resold in a way that blocks other people. Free public generation works only when everyone understands that the track is shared infrastructure.
Public libraries also encourage better creation. When users know the result may be public, they tend to describe usable scenes rather than private imitation requests. The service can block risky prompts and guide people toward mood, instrument, and use-case descriptions.
BGMFREE should remain generous at the front door. The value exchange is not a wall before creation. The exchange is that public free tracks improve the shared library, while premium options can later serve people who need longer, private, or higher-quality assets.
