When your parents listen to heavy metal you have to go "the extra yard" to find music that will annoy them.
Polkas or lounge music ought to drive those parents up the wall. And both still offer plenty of drinking songs. Heck, even techno-disco-electronica should drive a guitar lover up the wall (and the louder it is played, the more THUMP-THUMP-THUMP-THUMP drone there is to annoy with).
