Only one album visible in library?

[Nutul]

Hmm, I *think* the metadata is there.  Windows explorer knows about artist, album name etc when I look at the files.

It's always a hit-and-miss when it comes to Windows tagging software... (well, not always, but...)
1. sometimes FALC files are being tagged using Id3v2 tags (typical of MP3s, so...)
2. if everything is right, regarding the metadata, then the only things I can think of are
2.1. access permissions issue
2.2. unrecognized files (for some reason that escapes my mind)

But, TBH, I'd focus on (1.)
