Hi! I was pretty deep in to this a while ago, and I'm diving back in now. I am searching for a way to airplay Apple Music content to multiple Airport Express routers. I have tried Airfoil, Seedio, WHAALE, remote app nothing works.. I'm not looking to do individual sources per room. Just room management while using Apple Music. I'm not opposed to switching to Spotify, Tidal ect. anything streaming service that supports multi room airplay.
