I got put into Youtube Premium when Google Play Music merged, so I think of it as equivalent to Spotify premium, but also: you can also upload your own music library, you get ads removed on Youtube videos, and offline play for both music and videos.
It’s decently worth it if you reference Spotify Premium’s cost (and also I’ve been at 9.99USD/mo this whole time and not been hit with any price increases at all for some reason?)
The Pokemon go plus+ (yes it’s two pluses) is a little device, sister like a flattened PokeBall, rather than a service.
