I would think most of what you bring forward is quite common sense for musicians when they want to grow a professional career and earn money from their music. But I suppose its not. Thats why most of artists have managers I suppose :) And those who don't, I see them struggling most of the time. Like here on HIVE, I see some good artists, but sometimes wondering about the little effort they take to present themselves and their work. Some even producing more to try and get more rewards, while I think one shall be producing less but spend more time in marketing.
