Do you pay them any money to have the songs on the platforms?
If not, I wonder if they charge you a fee but only deduct their fee from your earnings. So if you don’t get plays then they don’t ask for money. And the break even point is at around 1 million plays. Just a theory of course; I’m sure it’s all stated in the fine print.
I was just curious about why 4 million plays is ~$20 and 1 million plays is less than a dollar.
