Just got an email saying my Echo will show up in a little more than a week, and I'm looking forward to hitting the ground running.
From what I've read, music sources include Amazon cloud, bluetooth smartphones, and any number of internet sources. But I didn't see any mention of playing music from a file server on your local network. Is this doable? Seems like a MAJOR oversight if not... unless its deliberate, intended to increase the usage of Amazon cloud. I suppose I could stick a 32gb card in my old unused android phone and stream from there, but that seems kind of convoluted.
