'"Free [music]" means [music] that respects users' freedom and community. Roughly, it means that the users have the freedom to run, copy, distribute, study, change and improve the [music]. Thus, "free [music]" is a matter of liberty, not price. To understand the concept, you should think of "free" as in "free speech," not as in "free beer". We sometimes call it "libre [music]," borrowing the French or Spanish word for "free" as in freedom, to show we do not mean the [music] is gratis."'
