Amos Vieux has said in-game that their favorite song is Dawson's Christian, because the Vic Tyler songs on the jukebox are all great, but they'd probably end up with a weirdly mixed playlist of breakcore and ULTRAKILL-esque music with much more chill Tragically Hip-esque music, for when they're high and not high respectively. If they were acting as chaplain, they'd absolutely fall for gospel rock.
Henri Vieux listens to classical music because he's an old fart. Ameile Vieux pretends she doesn't listen to music but hides Katy Perry albums and the sort in her dorm. Tom Larik probably listens to nothing but modern country and annoys everyone around him by playing it really loudly.
