Hi, i have a compilation album of songs with file names like this:
"- 100 Hits of the 90's - - 100 Hits of the 90's - 009 - Scatman John - Scatman (1995).mp3"

Is there a way i can fill in the artist, title and year from this?

yes:

The website is still in construction, as a consequence, some links may not work yet, for the older version (but without this tutorial):
http://eolindel.free.fr/foobar0.9/

Select files in playlist, go to properties and choose Automatically fill values and fill this as pattern:

- %album% - - %album% - %tracknumber% - %artist% - %title% (%date%)

In order to ignore the album part, use %% instead of %album%, same for tracknumber.

Thanks, this worked perfectly!
