T-mobile used to do this in Germany until earlier this month. In their FAQ [1], they state that the following in spotify count against customers' data plan: videos, album covers, sharing, and Spotify's "discovery" feature. They add a flat 100MB to the data plan to cover that. Note that the streaming of music is not included, so it doesn't count towards data usage.

They stopped offering this to new customers on August 2nd, 2016.

Swedens I believe largest operators 3 and Telia has unlimited or a large amount of data that doesn't count towards the usual data limits when using specially selected services such as Spotify and Facebook.

Telia also attached a condition that you had to promise to be nice on the internet and not practice "näthat"(net hate). Not joking either, they were then very unresponsive to criticism and questioning of their stance on net neutrality.

Here's one not from the EU, but Switzerland

Deutsche Telekom was doing this and advertising it in Germany a few years ago but they've since stopped[1]. Spotify data didn't count against your (usually very slim) mobile data limit.
