You could just as easily have an enthusiast who finds a few new indie albums per month and listens to them all the way through, or someone who leaves a top-40 playlist on in the background.
This just could not happen with what I’m suggesting.
Example: The band above, which earned < £200 must have at least 2 million streams a year = 166,666 a month
For simplicity let’s assume each of those 166,666 streams is a unique user. Each also listens to 1999 other songs that month (about 5 hours a day of music seems average?)
So each owes the artist 1/2000 of their £10 subscription = $0.005
166,666 streamers * $0.005 = £833.33 a month = £10,000 a year.
