A CHART FOR YOU: If a song is played 1.5 million times on Last.fm, the artist earns less than a penny. Way less. On Spotify, they earn even less! The chart also shows the artist’s share of tunes sold on itunes/Amazon, cdbaby, rhapsody, at gigs, etc. I can’t vouch for the accuracy, but the relative differences seem likely.
