I've discovered that listening to Sigur Rós is a bit hard for me, when i do - i love it, but it requires me to be in a certain mood, to fully appreciate the music.
It kinda makes all my emotions emerge to the surface, and that isn't always a good thing.
Even though it's really hard, i would say that Milano is my favorite song, the climax/chorus in that song gives me goosebumps!
Only heard Takk and ( ), they are both amazing in 2 different ways.
