Thank you for breaking the ice, @Mel. I have started a draft on Promotion strategies with better intentions than actual knowledge. We can discuss there whether this is useful and what you are referring to.
Other suggestions?
Collateral comment: I have been told that many music makers are not or don’t consider themselves “professional”, and that they keep getting back to “normal jobs” just to pay their bills. That’s of course fine and totally understandable. Please don’t take my words literally. Still, there are some music makers who are trying to build their career (or part of it) making music regardless of the difficulties and detours, while many of us are hobbyists and don’t try to turn this hobby into our career. While the words are imprecise, I hope we all understand the difference.
And again, it’s not that we don’t care about the hobbyists. It’s that we care especially about those who are trying to make a career, and the better things go for them, the better they will also go for the hobbyists.
