It appears to be difficult to collect a decent royalty these days especially from Pandora. Of course, Pandora thinks they pay too much and like all corporate toads have gone to Congress with their hat in hand and their million dollar lobbyist to request a special law that benefits them. Why won’t these companies just compete? It’s supposed to be a free market, not a rigged game.
Now most poets are true amateurs. They have no expectation of any royalties or compensation. The write because they enjoy it; they write because they can’t suppress it. Poetry, like all arts, is a winner take all market with a couple of well known people pulling in the majority of the money. They are not really better than many other poets, they are just lucky. But if you are one of those fortunate individuals don’t you believe it.
