Is that actualy what the payment rate is then 1000 plays for $10? If so that is poor. I do recall a Projekt email where Sam said it was 247 plays for one dollar also. Mmmhh not great.
Spotify's payout is not the same for every artist and it has been decreasing. The artist's payout can be closer to 0.001 per stream if they are signed to a medium or larger label. Thom B probably gets about 0.005 per stream, so that would be closer to 2000 plays for $10.
Mist costs $5 as a download minus 30% to a major merchant. So someone would need to stream 700 Mist songs (or the entire album 175 times) to produce the same revenue as an Amazon download. Streaming the entire album 5x per year for 35 years would pay the same as a download. This is assuming Spotify's payout rate doesn't change which is a doubtful assumption.
