Hi Ronnie, yes....they are fully populated.

Plus
And from the M brochure
� Meridian supplied �plug in� that allows imported CD to be correctly formatted for streaming system back up with full metadata
This needs reading carefully. But, the implication is that the meta data is fully retained (full being track level) exactly for the purpose of other systems (like Sonos and Squeeze) using the exact same data files. This is clearly by design and something that some of us have been utilising for a while.
