I was trying to connect to a Synology NAS to stream music from it.

I've successfully connected via FTP but the music doesn't play when I select the file.
Does the file need to be download then played? I was thinking the app would download it in the background, play it and then dispose of it when closed.

Local Network
But my main question is what and how do I set up the local network to stream music from a folder on my NAS.
