So, is the music on FMA free of copyright restrictions?
Some is, but a lot isn’t. Works that aren’t subject to any copyright restrictions are said to be in the public domain, which means you’re free to do pretty much whatever you want with them. A work on FMA could be in the public domain for a couple of reasons. First, it’s possible that its copyright term has expired. (Generally, until 2018, only works made prior to 1923 fall into this category). Second, it’s possible that the work’s rightsholders have waived all their rights. Most recorded music, however – including much of what you’ll find here – is copyrighted. After all, copyright protection springs into being whenever an artist writes or records a song. And, copyright owners have exclusive control over the bulk of uses of their copyrighted work, including downloads and remixes.
