There has been a lot of exposure to Sigur Ros on TV and radio indents and soundtracks (including the very listenable and uplifting Hoppibola), so there were no surprises here. It's mostly gentle, almost ambient, but not in a Brian Eno sense because you are consciously listening to it. Not understanding the language puts emphasis on the feel and tone which change. It is not boring, just different to most rock music.
