"Royalty-free" and Creative Commons are different licensing models, and neither simply means "free to use"
“Royalty-free” and “Creative Commons” are two distinct music-licensing models often confused with “free.” Royalty-free means the rights holder declares the song is not managed by a third party collecting royalties; such music is typically sold by a curated marketplace (e.g., Tribe of Noise PRO) that adds metadata, guarantees the licence is legal, helps if a copyright claim arises, and charges a fee. Creative Commons, by contrast, is a set of free public licences applied by the artist that grant specific permissions with conditions (attribution, non-commercial, etc.) at no charge. The key distinction: royalty-free is usually a paid, guaranteed-clearance product, while CC is free but places the burden of following conditions and verifying rights on the user. “Free download” says nothing about either — a track can be freely downloadable yet all-rights-reserved.
Examples
Tribe of Noise PRO: pay a small fee for royalty-free tracks with guaranteed legality and copyright-claim support. FMA CC BY track: free to use, but you must attribute correctly and accept there is no clearance guarantee.
Assessment
Explain the practical difference for a video creator between using a royalty-free track from a paid marketplace and a CC BY track from FMA. Which model shifts more risk onto the user, and why?
