Google has just released their new free streaming service available on any browser and in the US on Android devices (possibly IOS also but I can't check).
Ad supported it I presume is a Spotify competitor and getting ready to compete with Apple.
The app is not available in the Play Store (well it wasn't for me) but it's a trivial exercise to find it.
Apparently the playlists and stations are curated, whatever that means. I plan to try it out (I don't usually do streaming) since I have all my music in Google Music now so having more choices is useful.
