Add Local Files to Library over Local Network

[Nitrocide595]

I have a server PC (windows 10) at home and it has my library of thousands of my own ripped CD's and other music, all legitimate and in the correct format.  I'd like to include these in my "Local Files" in spotify on my main Windows 10 desktop. I clicked "Add a Source" and navigated to the server's music folder in windows explorer, but it it doesn't seem to be pulling music from there.

Again, I'm sure the format is correct, I have selected the proper folder, etc. but Spotify doesn't seem to be adding the local files to my library.  Is there a reason that this isn't working or is there some way to get around it?  

Thanks
