Amazon Music unlimited is £11.99 or £10.99 if you are a prime subscriber, not sure where you are getting that price. Family plan is however £19.99 a month.

I’ve tried several, many of them are free or have a free trial. I keep coming back to Amazon as being the least frustrating and they have pretty much anything I have gone looking for.

Check the Sonos music service listing page and try out any that look interesting.
