Ambient list by avg. trackratings

Since the day I bought my first album, I have this habit of rating all the tracks I hear by writing a score on little yellow post-its (I have a poor memory).
It seemed like fun to see what this would result into if I took the average rating for each album.
Most albums are ambient-IDM-ethereal related and to me ambient is pretty much everything that affects my brain, rather than my body. Think of the Namlook color codes from the early nineties :)
This is a long work in progress so the top positions will change often !
The best album here is not necessarily my all-time favorite, but it will be a very good overall album.
Hope you can find something new in here, and if you have recommendations in the same vein, I'd be happy to hear from you.
