On the finale, Hall reminisces: "Móðir mín í kví kví (My Mother In The Sheep Pen) is an old Icelandic folk song. The lyrics are based on Icelandic folklore about a woman who had a baby which she couldn't afford to have and left it outside to die, wrapped in a rag. The infant then becomes what we Icelandic call "Útburður" - the ghost of a child who has been left out to die. Some time later the woman wants to go to a dance but has no pretty clothes to wear. She is in the sheep pen attending to the sheep when she hears this whispering outside: "My mother in the sheep pen, don't you worry because I'll lend you my rag, my rag to dance in". It's a rather ominous lyric and this song is sometimes sung for Icelandic babies as a lullaby... a little odd custom perhaps. I remember my mother singing this to me. This is one of my favourite Icelandic folk songs, and when I created the music for "I Remember You", which is about a lost child that haunts people, I suggested to director Óskar Thór Axelsson that I should make an Icelandic choir version of it and use it as a theme / credit song. He loved the idea".

'I Remember You' is based on the internationally acclaimed novel by Yrsa Sigurðardóttir, the "Queen of Icelandic Crime".

"...the resulting score is as exciting as it is terrifying. Much like the film, Hall doesn't use jumps to get his message across. Instead, he layers sounds to create a feeling of unease. You can hear the industrial isolation coming through the music.... The mark of a great score is that it shouldn't matter if you've seen the film or not to enjoy it and 'I Remember You' is a great score" (Vital Weekly)
