This is interesting, spotify is paying $0.00029 to an artist for each stream
eg. 3500 plays equals the same as selling it on iTunes
Whats really interesting is that the artist feels that giving it away for free and getting an email address is more valuable (eg a ReverbNation model) actually makes them more money.
eg. upselling CD's or tour tickets or band shirts etc.
What are you thoughts? as a Spotify user would you give away your email address to help out artists you listen to?
