Special Feature: Stuff your parent's like

Hopefully a regular special feature here: Stuff your parents like!

I got my mother onto listening to CBC radio - http://www.cbc.ca/radio/ (we're canucks eh) one day last year when she was surfing through my saved stations in the car. Now she only listens to CBC radio. I'm glad there's no more adult contemporary crap to endure, but sometimes she's excessive: spending entire weekend afternoons with opera blasting in the living room. Someone help?
