Spotify has had a severe and negative effect on musicians who make what I term 'peak experience music'. Amazing music, but not something you listen to every day. Say you listen once a month or even just a few times a year.

Before: 2 listens = dealer price of a CD in UK = about £7.5 (on a good UK indie that's split 50/50 with the artist).

Now: 2 listens = income from 2 streams on Spotify = about £0.0006

I'm thinking of artists like Autechre.

Spotify is starting the shape the sort of music that artists can be successful with, in a bad way.
