Mubert

Mubert generates background music by genre, mood, BPM or theme rather than from a written prompt, aimed squarely at people who need a soundtrack rather than people who want to compose. Both subscription and perpetual-licence purchasing exist side by side, which is unusual in a market that has mostly moved to subscription-only.

The free Ambassador tier gives 25 generations and 5 MP3 downloads a month, but requires attribution and is non-commercial only. That is a real, usable tier for a hobby project with a credit line, and a non-starter for anything monetised.

Read the licensing terms closely

Creator at $11.69 a month billed annually, discounted from $14, raises the limit to 500 generations and unlimited downloads with WAV export, but the plan is still explicitly non-commercial only. Mubert states plainly, on every tier, that tracks are not licensed for Content ID, standalone release on streaming platforms, or stock music sites regardless of which plan you are on.

That is worth reading twice before assuming a paid plan clears you for whatever you want to do with the output. A YouTuber worried about Content ID claims, or anyone planning to release a track to Spotify, needs a licence tier beyond what is described on the standard pricing page, and should confirm the actual terms directly with Mubert rather than assume Creator covers it.

Where it fits

The API is the differentiator against most consumer music generators: a developer can embed generative background music directly into another product rather than manually downloading tracks. For a straightforward creator just wanting music for a video, that matters less than getting the licensing tier right for the actual intended use.
