Yeah, Amazon music works OK, but it’s a bit tricky with names. I had both my Sonos and bedroom Echo named “bedroom”. It didn’t like that, OK fine. I renamed the Sonos to “bedside”-- didn’t work, played on the Echo every time. Tried renaming the Echo to “Bed”, no go, still played on the Echo. I had to rename the Sonos to “Sonos”, then it worked.
I would not have bought a Sonos, it was a gift. Great sounding speaker, but I don’t like using its app. I setup an airplay daemon and mostly use that instead. Works OK, but there’s a fair bit of latency so not ideal.
