Go to the app, add music service, pick from about 30 sources and just install them in.

You can then select some as favourites so they always appear on the first tab. Useful for radio stations.
I use Alexa and can add the Sonos as her automatic output speaker for music.
It’s not been as good since bbc went off it, and I also use tidal which doesn’t have Alexa Sonos support in the uk. (so have to use the app).
If you want Spotify, Apple, Amazon music etc though that’s all there.
I can also steam directly from the Tidal app to any Sonos. Presume Spotify etc work the same. Edit - confirmed above by PD.
Hope that helps matey.
Edit. Just installed google home App and that also picks up the Sonos’s as destinations.
