Advice on import of large music collection

[Roy Boy]

So I downloaded Metadatics to try that approach. I converted one album (Beck - The Information) to FLAC using XLD (using default settings).
I imported to Metadatics and used the MusicBrainz option to find the album metadata...This seemed to work nicely. I updated my Synology with the latest version of Minimserver ..I copied the newly tagged album to the Synology and did a rescan of Minimserver. After the iPad control point app for Lumin finishes its update after the rescan...I can see the Beck album under the Artist search function..I select the entire album to play...Unfortunately none of the tracks will play..The Lumin app cycles through all the songs in the album but will play none. For grins I point the Lumin app at the Synology Media Server also running on the NAS just to see if it will play the album...I get the same result..
I am wondering if there are some options on the XLD conversion to FLAC that would make this file incompatible for play in Minimserver? I looked at the Minimserver log and did not find anything. Thanks for any insights.
