Sonos and iTunes

I have the Sonos Connect and a Bridge connected to a NAS drive (LG 2TB). Everything is working perfectly. I connected both units with ethernet cables as I had them run anyway to my rack. I go analogue out to my multi Channel Cary Amp to play music outdoors and I go digital to my Theta Pre/Pro to play music on my main stereo when I am too lazy to pop a CD into my player. I use the Sonos App on my droid phone to play all my music. My wife and daughter just love the Sonos App on their iPhones they are always changing my music selections the little brats! Perhaps I gave them too much power.

As I do not have any experience with iTunes I’d like to help my daughter play her songs from iTunes (Not from her hard drive) through the Sonos. Can someone please give me step by step instructions on how to do this? I have read the instructions on the Sonos site but i just don’t get it.

Thanks you very much!
