I love this idea! I chose some music for Franz Kafka's "The trial"
This is the list so far, but I will keep working on this:
Philip Glass - Metamorphosis Two. This is for the beginning, when Josef K. thinks that everything is just a mistake of the system
M83 - Solitude (Felsmann + Tiley Reinterpretation). The atmosphere is getting more and more soul croushing, the main character is starting to think that he is lost.
Lapse - Black Math. Well...
"Smile when you're not afraid to die
But I'm afraid with each goodbye
Lost the sun above my head
Lost myself in things"
(...)
When you are numb
I'm forgiven
I'm forgiven
When you've been gone
Lost in the lapse again
Lost in the lapse again"
Polaris - Masochist.
"I've got this cold black silhouette hanging like a marionette
Casting a shadow, a shade on me
Just a sick, sad, sorry mess, living like a masochist
Your worst impressions were right about me"
