the majority of music will ALWAYS be bad. that's just how stuff works: mediocre people make mediocre music, they're mediocre at their jobs, etc. the world goes round. complaining about that is like complaining about rain. but when you have more musicians, you're going to statistically also have more BETTER musicians>>3251942
it's always been a struggle (like any line of work) but it's changed dramatically. even the absolute highest level of the industry is barely making money anymore, and that's with them STILL taking 99% of the profit of any of the musicians they "own."
and it has nothing to do with principle, that's just how people work. as a rule people don't buy for the long term. and that's the absolute only benefit that buying music has to anyone at all, in addition to it being less convenient, more difficult/impossible to obtain a lot of music legally, and other difficulties
