If you are using batch import, it's very limited at the moment in terms of populating those fields automatically. The batch import has an option to use folder structures to populate Artist/Album/Genre, but this can be tedious to set up. People have asked for more powerful features in terms of filter patterns and the like for limiting which files are imported, and a pattern recognition feature that could extract sections of filenames out to use for various song fields. This will all take a fair amount of time, so I'm not sure I can get it into the next update, but it's definitely high on the list of things to do.

As a side note, you can also supply default values for the fields at the bottom of the batch import dialog if you don't like "Unknown". In the next version, all of the fields are actually optional, so you won't even need to have an artist/album if you don't want to.

If you use the song editor, it's pretty easy to just enter the values into the various fields.
