I get missing the old service. We went with a YouTube Music subscription but I'm not particularly happy about it. I loved Play Music and when it folded we just kind of went with the flow. Now there are reasons for sticking (the cost isn't bad, we have a family membership, and we get no ads on YouTube).

The "radio station" functionality has been great for me. I do most of my music listening while on the motorcycle, and it's easy to thumb things up and kick off new radio stations via voice commands. So I've been able to meander through various musics and have had a pretty continuous stream of artists I wouldn't have heard of.
