In the USA, as I understand it, whether you sell anything or not is irrelevant. (At least in theory. See next paragraph.) If you make a recording and distribute it, you owe the copyright fee.   Assuming, of course, that the song involved is within copyrightable dates (generally speaking, originally published earlier than 1923.)

There are those who figure, "My pressing and distribution is so small, they're never going to hear of me, much less come after me." This may be true or not, but I'm not telling you to do it. That's for you and your own conscience.
