It was really hard for me as well, because i wanted to include songs like Lost in Moments, Hallways of Always, The Future Sound of Music, Like Music and All the Love (just to name a few), but its damn hard.
I haven't listened to the Williams Blake-album yet, how is it?
And i think i need to give Kveldssanger, Lyckantropen Themes and Svidd Neger a few more listens before i can say i know them.
