Spotify removes silent album that earned indie band $20,000

Is encouraging people to listen to your music "while sleeping" on Spotify the equivalent to a blogger asking their audience to click on their AdSense ads?

In this case, it seems the "silence" is the issue and not the fact that the band asked it's fans to steam while sleeping (although I could be wrong). If so, I wonder what the threshold is ... what if the song included minimal sound?
