I have recently found the website "Songmeanings" which you probably already know about and found this site interesting
(I was checking a song by Laura Marling which I found beautiful ans intriguing).

When I checked Heather Nova's songs, I was surprised to find out that her songs were not largely commented
http://www.songmeanings.net/artist/view/songs/6193/

I thought that maybe a post on her forum could help
I will try to add some comments myself
