Belkar - Showtunes (He only poses for the heavy metal album covers)
Elan - Listens to everything, but has a preference for classic rock
Durkon - Led Zeppelin by cultural preference, country music by choice. They're the only ones that speak correctly.
Roy - Secretly, Elan's music has grown on him, but he won't admit it.
V - Music is a distraction from my studies.
Haley I can't quite decide, sadly...

Tarquin - Anything by John Williams (inlcuding the Imperial March, of course) or Danny Elfman. They know how to set a scene with their music.
