hey, i have my iTunes music saved to my external hard drive which is plugged into my router. i can access the folders and play via 'readyshare' which is through my wifi network. what i was wondering is how i can play them by opening iTunes and having that detect the external hard drive? I've gone into preferences and set the library to use /Volumes/USB_Storage/iTunes Media but they don't show up in the music tab of iTunes. any ideas?
