I think Spotify needs to implement Siri support so I’m not surprised that it doesn’t work on the beta. I’m also excited for this integration because I loathe Apple Music. Spotify is so much better. It’s annoying that Spotify doesn’t work as wel natively. If Apple Music was just a Spotify clone, I’d happily switch to them just for the first party support, but they insist on making it different. Spotify’s interface and music organization is just so much better.
