Royalty Free music licenses give the right to use copyright music without the obligations to pay royalties for recurring use. This is a big advantage as it simplifies music licensing by removing the need to deal or otherwise negotiate licensing fees with the PRO’s (Performance Rights Organizations). Royalty Free is the type of the music license that allows the buyer to pay ONLY ONE-TIME PAYMENT for the music license and use the music as long as the license allows. There are different Royalty Free license types, which might differentiate by audience type (Youtube, vlog, podcast,..) and/or the number of listeners (limited to a certain amount or unlimited), more details visit royalty free inspirational music
