It's very hard to make a living out of music. It's easier than ever to create some but making a living wage? I think a lot of "long tail" bands are doing it on the side. Patreon was supposed to change this but https://graphtreon.com/top-patreon-earners/ there's like one "creating music videos" on the top earners here and even this list ends with a $26k monthly income which is not much.
