Most are free-to-use (ie public domain or copyright-free) meaning the words can be copied and sung to at least one tune with no concerns about copyright or performance licensing. Many such hymns are old/traditional - but where possible a variety of styles / genres are included. A small selection of hymns that are still be copyright may also included where they are a particularly good for for the theme(s).
