There is a new advert by Orange which ends with the statement Relationships get better with time and has an older couple dancing together while doing household chores, I don't suppose anyone knows if this is Sigur Ros? It sounds very like them, but I can't think of which song.
i know it i think... well im pretty sure...have u ever seen the film the road to perdition..well its the main theme from that...i was looking for the same song then remembered it from that film....if you use a music downloader u can find it but i dont think you can get it on the soundtrack
