Multiple users for one set of hardware

He or she will see your music in the Sonos. There is the ability to add their account also should they need to. They will see their music that resides on their actual phone (not downloaded from steaming service)

@Chris so the music list is stored on the accessing device? But how is that possible? I see the same list on my phone, my iPad, and my computer.

Sonos hardware stores nothing. MuSic comes from computer hard drive, phone, or internet source

Your music source is probably network service - Sonos is pointed to that

Chris,

This is where I can see some future potential for Sonos development happening. It would be nice to take the 'My Sonos Tab' ...(stored in Sonos' own cloud and within my account) ...with me and when I’m out and about at a friends house, to load up their Sonos system, but also see my own 'My Sonos' favorites tab. I could then play some of my own favourite playlists etc...

It would be like taking my vinyls round to a mates house to play on his/her hifi.

Those were the days !

...Maybe one day perhaps?

If you use favorites on service like Apple Music or Spotify then you can.

If you use favorites on service like Apple Music or Spotify then you can.

I do use Spotify Premium and Amazon Unlimited ... and I have playlists and favourites in far 'too many' locations, but it would be nice to be able to access the 'My Sonos' tab too... for me at least, as all my playlists everywhere would then be viewable through the one App.

Go to Spotify in Sonos and go to a playlist you want. Hit the ... top right and it will put it into my favorites.

If went to friends house. Add your Spotify account ... do same if you want etc.

Sorry, still confused. All my music is in the cloud - my Google Music account, my NAS, my Pandora channels. So if someone else walks into my house and fires up his Sonos app to connect to my speakers...how does he see my music list?

The Sonos devices store the music index associated with your local music library so anyone connecting to your Sonos system will see that list on their controller.

I believe that something similar to that is true for most other music sources as well. You connect to a Sonos system, the controller retrieves the local service information and shows it to you using the accounts and passwords entered into the local system.

Now for something like Spotify (which I have no clue about so this is iffy) that has Sonos control built into their app I believe it will always see your system since it isn't connecting to the local Sonos system but the Spotify server on the Internet.
