Why not have just ONE Music Library??

e.g. I have just One Library on a NAS with the typical Folder (Artist / Album / Track) layout

iTunes manages this Library and plays from it where required

But SqueezeCentre and Sonos point at the SAME Library on the NAS......build their own Library Indices........and then play from it when asked to do so

Managing One Library is much simpler and easier to work with.........the NAS and Backups can easily take care of security issues
