music licensing
Royalty-free music, or RF, refers to the right to use copyrighted material or intellectual property without the need to pay royalties or license fees for each use or per volume sold, or some time period of use or sales.
An open standard is a standard that is publicly available and has various rights to use associated with it, and may also have various properties of how it was designed (e.g. open process).
A Creative Commons (CC) license is one of several public copyright licenses that enable the free distribution of an otherwise copyrighted work. A CC license is used when an author wants to give people the right to share, use, and build upon a work that they have created. CC provides an author flexibility (for example, they might choose to allow only non-commercial uses of their own work) and protects the people who use or redistribute an author's work from concerns of copyright infringement as long as they abide by the conditions that are specified in the license by which the author distributes the work.
Works in the public domain are those whose intellectual property rights have expired, have been forfeited, or are inapplicable. AKA open copyright license
Creative Commons licenses are explicitly identified as public licenses. Any person can apply a Creative Commons license to their work, and any person can take advantage of the license to use the licensed work according to the terms and conditions of the relevant license.
Free licenses are a popular subset of public copyright licenses. They include free and open source software licenses and free content licenses. To qualify as a libre license, a public copyright license must allow licensees to share and adapt the licensed work for any purpose, including commercial ones. Licenses that purport to release a work into the public domain are a type of libre license.
Free music is music that, like free software, can freely be copied, distributed and modified for any purpose. Thus free music is either in the public domain or licensed under a free license by the artist or copyright holder themselves, often as a method of promotion.
