Genrenator vs Jamendo

Genrenator is a novelty API that invents random music genre names and short genre "stories" by recombining fragments — instruments, beats, adjectives, prefixes, suffixes, and regions — drawn from Spotify's Every Noise At Once genre database. It's a keyless WordPress REST endpoint (GET /wp-json/genrenator/v1/genre/ or /story/, optionally with a count suffix like /story/25/ for multiple results) that returns plain JSON strings, free to use with no documented rate limit.

Jamendo's API serves a catalog of roughly half a million independently released, Creative-Commons-licensed tracks, with over 20 read methods covering search, radios, and discovery plus write methods for managing a signed-in user's library. Reading the catalog only needs a free client_id issued on signup — full OAuth2 is reserved for the endpoints that act on a specific user's account — and responses can be requested as JSON, pretty-printed JSON, or XML. There's no published pricing tier for API access; it's free to use under Jamendo's terms.
