How much do you think I am paying an artist hen listening to their songs on Spotify 1000 times? Every album they ever made, dozens of times. The answer will surprise you!
Already every single musician has to be a personality and marketer. There is no other way to make money. You can not finance yourself by the rights to your music, right now.
Only a very select group of artists has any kind of real revenue from the rights over their music. The rest is already using other channels to profit, which are not protected by IP.
As much as you might think cherrypicking examples like Spotify (and characterizing them poorly, besides) supports your point, I don't think it's going to be practical to enumerate every single source of sales, royalties, and other fees paid to artists in aggregate.
So maybe you'd like to state, for the record, that all those sales, royalties, and other fees—in aggregate—are so small as to be meaningless and insignificant to those who receive them? It's staggeringly wrong, but at least then we'll know where we stand.
