Purple Planet is a small studio's own catalog of original royalty-free instrumental scores, offered free with attribution or via a paid license without attribution.
Value is a curated, single-source catalog of professionally composed background scores across moods and genres, rather than a huge undifferentiated pool.
Fits personal projects, social content, and hobbyist videos where crediting Purple Planet in the description is acceptable; commercial productions should buy the license instead.
The free tier requires an on-screen or description credit and isn't registered with any performing rights organization, so no royalties are owed; a YouTube Content ID claim can still occur on free-tier use but is resolvable by adding the credit and contacting Purple Planet, while a paid commercial license removes both the attribution requirement and the claim risk.
Musical scores you can license or use with attribution.
