Roon nucleus doesn't work as advertised

Trying out Roon what a mess

an imac with a thousand or so tracks, a pc with 6000 or so some in itunes some thru windows media and my wifes iphone with about 500 songs all on the same network and the nucleus only sees the streamer.

Settings->Storage->Add Folder?

BTW - Although iTunes is supported, WMA files are not. If you have WMA files you’ll need to convert them to something else, e.g. FLAC.
