They haven't recently changed the rules. The average for terrestrial radio in the US is around 12c/play.
In the UK it can be up to £15/minute plus £35/play on a top radio station like Radio 1. Less mainstream stations pay less.
The artist may see half of that depending on their publishing deal.

Around 80% of Spotify revenue goes to rights holders - i.e. a handful of big record companies.
Around 10% of that 80% goes to artists. [1]
The record labels keep the rest.
[1] The exact accounting details are byzantine, especially in their creative use of expenses which diminish apparent revenue. They also vary from artist to artist. Top artists get a much bigger cut than newly signed artists. But no one gets much from Spotify plays when compared to radio payments.
