Quick question

Hi guys,

Thought I might as well sign up as I'll be purchasing a couple of the play 3 or play 5 speakers soon.

I just have one quick question, it says you can play music from your phone, tablet, iTunes etc. can each app only play the local library?

For example from the app on my phone, could I only play my phone library or would the app pick up my iTunes library from my laptop? and any music on other devices on my LAN?

This probably won't affect me buying it but thought I'd ask in advance, cheers

Chris
