I would argue that it depends largely what you are trying to accomplish. For the longest time, I was very hesitant in posting my music on any social media platforms.
On one hand, it is a very good way of promoting yourself to others, and potentially might lead to the right people becoming interested (even if you have a small following).
However there is the other view to consider. Are you posting music for self validation, and looking for others to appreciate your work? Are you letting the number of views or likes dictate your creativity?
Maybe not. However slim a chance, we as humans are always influenced by others.
I would caution against promoting yourself to make yourself feel better about your music (i.e. more clicks and likes equals a better track).
I’d say that self promotion is critical in today’s music environment. Thousands of composers are looking for the same opportunities, and while not actively fighting each other, it is quite competitive. Promote your creativity and differences, not what pleases the majority. Eventually your originally will win out. The right people will get interested.
I wouldn’t worry so much about others and if “they can be bothered.” What matters is that we are doing what we love.
