So we just did some math in a discord server
According to some stats we found online, the payout on spotify is 0.00437 cents per stream
I looked up the length of my most listened to song today (4:21 minutes)
It would take me between 34 and 35 days of listening to that one song straight to make the artist 50 cents. And that's only if I'm listening to that one song on a loop 24/7
The most expensive spotify subscription is 10€ per person. The cheapest one (afaik) is a family subscription that is actually shared by six people, costing 15€ per month.
So Spotify Premium subscribers pay between 2.50€ and 10€ a month. And far less than 50 cents of that are paid to the artists (And my guess is the label eats up much of those 50 cents)
