Just tried switching to apple music for the 10th time. Spotify is just so much better for recommendations and while spatial audio is neat the only way to find out if something is available in it is through the promoted playlists or playing the song and seeing if it says Dolby.
I have car thing and while it’s better than pulling out your phone I still wish I had carplay. Have you tried “hey Spotify” on car thing? It hasn’t heard me correctly a single time even parked with the AC off.
