I've seen financial reports from an independent artist (distributing through CDBaby). Here's the figures:

Spotify: $0.0022 Deezer: $0.0022 LastFM: $0.0005 iTunesMatch: $0.003

These vary very slightly from time to time but iTunes Match has regularly been the highest.

It varies by month, by country, and by record label. So it's hard to give an exact figure for every artist. $0.003 is on the top end of the scale though.
