I only use folk dance music to teach my fitness classes. Do I still need a SOCAN licence?
You may. Even though much of folk music is deemed to be “public domain,” either because its creator is unknown or has been deceased for more than 50 years, much of recorded traditional folk music is “arranged” (different parts are created for each instrument or singer), and those arrangements are subject to copyright and SOCAN licensing. Make no presumptions; you are responsible for submitting a program to SOCAN for final determination.
