Royalty-free music refers to music that you can use without paying recurring royalties or licensing fees every time the music is played. Once you buy a royalty-free track or acquire a license for it, you typically have the right to use it as many times as you want, without worrying about additional costs. It’s a cost-effective solution for content creators, businesses, and anyone in need of quality sound without breaking the bank.
