Server doesn't see certain albums

[swdick]

I am in the process of ripping my cd collection.
I check every now and then if Minimserver sees the new files. I restart Minimserver and can see most of the new files but some are not to be found in the control point (kazoo).
For instance: I ripped Die Winterreise (Christoph Pregardien) can see it in my Files but not in Kazoo when looking for Composition though the Composition tag is set to Winterreise. Cannot find the artist either.
It seems to depend on how I look in Kazoo: folderview or otherwise (?). I am confused here.
