Help with Scandinavian female folk singer needed...

OK, this is going to be tough, folks...

I heard her on the car radio and was blown away. And, I was sure, I wouldn't remember a THING at home: Neither her name, nor the song title. And, what can I say: I was right ! I do remember the tone of her voice (which was beautiful, but impossible to explain), but nothing else. Well, almost:

- Her last name was 2 syllables (like Ahden, Arden, Amen, something of that kind)
- The song title was something like “homage to …” or “love letter to …” or “prayer to …” with a name., but the name wasn’t a human. Instead it was her guitar
- Very light company (couple of instruments, playing folk like music, her voice definitely being the most important part
- I think she sang In English
- Not one of the recent Jazz singers (on ACT label), I’m pretty sure.
- When I say Scandinavian (that I’m sure), I think she was Norwegian, but could as well been Danish.

OK, I don’t expect somebody to solve this puzzle, but if you could come up with some Scandinavian singers names, I might recognize her.

Please, help !!!

Cheers
Stefan
