The reason the music industry is in any kind of trouble is because of how the companies that control this industry are not, in effect, effectively growing the industry, mostly because of incompetence, not being artists themselves.
There are not enough artists in society.
Artists are the ones who dream the dreams that become tomorrows reality. Art is what lifts up your day and get you out of your troubles, etc.
When art degrades so does society.
The companies that run this industry are like vampires making money on artist's creations. (Part of it are our own fault since there is this popular consideration that if you are an artist you should suffer as that gives you more to "draw" from. Also nonsense, but so true to most of us that most makes sure they suffer. As a result they think that cannot properly and effectively handle themselves and that they let these companies control their output.)
The same companies are not only incompetent in many things, but helping artists grow strong is not on their agenda. Strong artists are a threat to them, rightly so given their criminal level of exchange.
If you wonder why any art form is suffering don't even think it's because of too much competition as that will never lead to a solution. Now if you don't want a solution then you should promote this idea that there is too much competition.
BTW, "just good enough", comes from the same companies. They are the ones releasing it.
As a note, which is known to established musicians, the only way to make money is to tour since the labels keep 90% of the profits.
