Right now, a user is able to toggle their 'Recently Played Artists', but are only able to do so if they allow it within the social settings of the downloaded desktop version of Spotify. Those parameters are more and more restrictive, especially with majority of users utilizing the app solely through their mobile sevice. There is no option to do so on mobile.
I'd like to see what music the users I'm following are and have been listening to (should they want to do so). Simply add this toggle option to mobile devices.

Hey there, thanks for posting your idea.
Keep in mind that this is now possible to do on both Android and iOS devices from the app's settings.
