here you go, this is a breakdown by platform from nov 2014 to may 2015
however, two things to say about this:
1) We were with ST Holdings for years and spotify had climbed up to a clear second place while we were with them. When STH closed down and all the label's catalogues were removed from the stores while they were moved to new distributors (who then reupload all the content to the platforms) we suddenly disappeared from all the spotify playlists that we'd been included in which resulted in a sudden drop-off in spotify revenue. This explains why it's further down the list than it was previously.
2) Spotify is growing month-on-month for us so while this relatively long-range set of numbers shows it in 3rd place it's pretty much climbed back up into 2nd place again in the last couple of months. The slow first few months is dragging its aggregate position down a bit.
Thanks for posting that, really interesting. That sucks about being removed Spotify playlists though.
