What Eliza also said (and I did too) is that you decide for yourself what you rate and what you want to listen to, or not.
People will do (and play and sing) stuff you don't much care for.
They are allowed to and (sometimes inexplicably) make money out of it.
It's useful (both in marketing and in aesthetic terms) to define exactly what you are talking about.
That's accuracy and has nothing to do with exclusivity.
