But its not $10 for all music ever created any more than its $15 for all the food on the buffet at Golden Corral. Its all you can eat, not all the food. There's only so much music that can stream through one set of speakers in a month.
Blind Pilot was half the OP's playlist. They'd get $5. How many artists would kill to get $5/month from their fans?
The real problem is that Blind Pilot might have gotten a whole penny from the OP's month of patronage. That's the part of the system that's broken. The part where fans can choose from all the artists that have ever created is a feature (and a damn good one), not a bug.
I'm starting to think that beyond "not pirating", we have some moral responsibility to make sure that the money we do "pay" for our music actually makes it through to the creator of that music, otherwise we're just buying moral absolution from immoral middle-men along with some (lazy) convenience.
Edit: 'Egbert' is way ahead of me!
