I have installed a NAS drive and My Cloud Home on my Sonos. I have dragged and dropped all of the music albums in my iTunes library to the NAS drive. Almost all of them are then available from the Sonos My Cloud Home library menu, and play normally. However, there are a few music which will not show up in the My Cloud Home library menu - even though they are present in the data files on the NAS drive. I have deleted and re-loaded the data more than once - but the same few music albums refuse to be available in the My Cloud Home view.
