This. It's highly unlikely that some SVP would respond so swiftly (no pun intended) to a pop star.
Given public presence and the way they are steering Apple Music, the personal response - regardless of planning - is less surprising.
They might have been going with the "shared risk" model of free up front play, but bigger payouts to the artists on the subscriptions - but still had their "Apple takes the risk" on the front end, then payouts are smaller on the back end.
Then when artists grumbled about the shared risk model, they kicked in with the alternative model.
