To get a better impression, all that would be needed is for a few indie artists to disclose how their payout rate is calculated down to 1000 streams per provider...
I'm still waiting for a streaming provider that pays so fairly that the subscription fees are distributed proportionally to what the user has actually heard. For example, if I pay 12 €/month and have only listened to one artist in the whole month, it should be obvious that this artist gets, for example, 70% of the 12 € and the streaming provider gets the remaining 30%. But I'll probably have to wait forever for that...
Mittlerweile haben ja schon einige große Onlinehändler einen Marktplatz in ihren Online-Shop integriert.
Auf anhieb fallen mir da z.B. ein:
Conrad.de Kaufland.de
Media Markt Otto.de
Voelkner.de
...
Für Bücher und Medien gibt es z.B. auch noch Booklooker.de
