I picked the song ” Welcome to my nightmare ” by Alice Cooper for Kazes character. I feel like it really goes along with Kazes dark and mysteries vibe. If Kaz was in a some sort of dramatic soap opera this song would probably play every time he entered the room.
The other song I picked was “Fade into you” by Mazzy Star for Nina and Matthiases love thing that they have going on. They are basically mortal enemies but they still love each other without meaning too. I think when the book writes about Matthias and Nina being stuck together for weeks is when they started to fade into each other.
Anyways both absolute bangers, they are very old songs tho
