Thank you for your question. Yes, you can have up to 32 of our products on one system all playing the same thing or different sound in different rooms. We have over 150 streaming services you can use with our system and Pandora is absolutely one of them! If you want to use Sonos One as surround sounds you'll need two of them. Also, you'll need to separate them as surrounds every time you want to use them in other rooms for music. If you don't, they will be part of the Beam as a home theater system. This is very easy to do in the app.
