Play Music has not been shut down (yet), and you can transfer everything to Youtube Music, which is available at the same price (and in my opinon a superior product).
Some randomly selected people can transfer everything to YouTube Music. I can't, and it may be months before Google would allow me to. It's exactly that kind of treatment that makes me feel like Google has zero respect for its customers.
Spotify is generally better than Play Music though, so it was for the best in the end.
