"Royalty-free" means you're licensed to use music in your videos without paying for each use, copy, or sale—but it doesn't mean the music is free or fully covered.
Some royalty-free music still requires you to pay royalties to performance rights organizations (PROs) for public use.
Epidemic Sound goes beyond royalty-free.
We own all economic rights to our music and are not affiliated with any PROs. This allows us to offer a direct license that covers all usage rights—including public performance rights—worldwide.
