Spoiler! Maybe?
RAUS! RAUS!!!
The song "Hero - Skillet" is a perfect fits for Rune. With the near last chorus into the last chorus being Rune awakening his ember.
Then "Pheonix - Fall Out Boy" is Zerek (I got his name right. Right? Alon's mentor, Mr. Rat)
"Not Gonna Die - Skillet" for Max's route maybe?
"Be Somebody - A Thousand Foot Krutch" for Burry.
