The music Brian listens to sucks pretty hard
Sounds like some freakin' spoken-lyrics punk music. Did any of the crew themselves make that music just for the movie, or does that mega-crap actually exist? Like, legitimately? Something people listen to? Even Killer Klowns From Outer Space has got better music, although, admittedly, it's never just heard through headphones for a few seconds... they might not have seen a point in making good music.
