Spotify doesn't make profit from music streaming, despite having over 400M monthly active users, because it pays two-thirds of all its revenue to the rights holders.
My Spotify wrapped had a special message from Weird Al (I know, I have great taste!) with the following:
“It's my understanding that I had over 80 million streams on Spotify this year. So if I'm doing the math right, that means I earned $12, so, you know, enough to get myself a nice sandwich at a restaurant. So from the bottom of my heart, thanks for your support. And, uh, thanks for the sandwich.”
