Since I just recently registered my Sonos account in my Sonos system I've just discovered Spotify Connect and while evaluating this and trying to figure out how the two systems worked I realize I'm quite puzzled by the situation.
If I understand this correctly, anyone with access to my Wifi can now play Spotify premium on my Sonos system. The Spotify registration in Sonos doesn't matter. Is this correct?
Also, what is the actual purpose of the Sonos account required for Spotify Connect? Just out of curiousity I registered with another e-mail in Sonos and as far as I could tell it had no impact on Spotify Connect at all. Actually, as far as I could see that account has no impact whatsoever on my system. Or is there any aspect of the system functionality that is affected by which Sonos account I use?
And finally, now with Spotify Connect in action, does the Sonos App/Controller make any difference as long as I use Spotify Connect? I noticed Spotify can kick any listener out from a speaker in Sonos so there's no superuser status or anything like that? I noticed combining zones and settings like EQ requires the Sonos App but for ordinary playback actions I really don't need it do I?
