That's not an issue, that's accurately reflecting reality. If I'm paying the same $10/month just to listen to $OBSCURE_ARTIST for 10 plays per month, then each play of that _is_ worth more to Spotify than each play from a 10-year old listening to the same track of $SUPERSTAR one thousand times in a month.

In one case, 10 plays brought in $10 of revenue to Spotify, and those 10 plays should get $PERCENT of that $10.

In the other case, 1000 plays brought in $10 of revenue to Spotify, and those 1000 plays should also get the same $PERCENT of that $10.

A fixed monthly subscription amount with unlimited usage will always carry this deficiency. A solution that addresses this would be usage-based pricing.

That's not an issue. That's the entire point. You track listens per account and if you're only listening to a single niche musician, all your money (not someone else's) goes to that musician.

The real mystery is why it should work any differently, because the cross subsidy seemingly creates a perverse profit incentive for bots to scalp off some of that cross subsidy. The economics are broken. This is socialism for the rich and popular.
