George,
I do not think the slimserver allows you to do that. However, there's a free software called "Media Monkey" that will allow you to tag, re-tag, auto-tag all your songs, and it will allow you to generate all kinds of statistics on your collection, including exporting a list of album into .CSV (excel) format. It is quite user friendly, one of the things that I like is the "auto-tag" feature which it can go to Amazon.com and re-tag every song that wasn't properly tagged before. Once you did the tagging in MediaMonkey, it will automatically save into the FLAC file, and the new tag will be recognised by slimserver.
Best regards
