I didn't think it was possible, but Deezer pays artists even less than Spotify. The same track has paid $0.00300932 from Spotify and $0.00282121 from Deezer. Also, Spotify has far more users, and our current sales on Spotify are more than 15 times higher than Deezer over the same period. So from a musician's point of view, if I could only choose to have our music on one of them it would have to be Spotify.

From a listener's point of view, there doesn't seem to be much to choose between them.
