“Royalty Free Music” is a term that refers to production music (music created for commercial applications) that has no additional fees to pay once the music has been licensed. It is paid for once, and (depending on the license or company selling it) can be either used a single time or multiple times. Uses for Royalty Free Music include television, film, documentaries, web (your YouTube videos!) and beyond. Especially if you plan on making money or are a Youtube partner, you need to make sure the music you use is Royalty Free to avoid getting your videos removed or paying huge fee’s to labels, producers and songwriters.
