The ideal "Nostrify" app would allow you to zap (or some other V4V scheme) directly to the artist or DJ and give listeners the option of easily volunteering to help host the distributed content bucket. The "what are my friends/idols/tastemakers listening to?" (audioscrobbling) feature is a desirable complement to giving artists an alternative independent platform for disintermediated promotion and higher pay-per-stream income than Spotify's going rate of $0.003 (12 sats).
