My music...

Last night, I had the boys bring over a couple of their friends from co-op to play at our place/go sledding. I had to make a stop at Target to pick up some hamburger buns. While I was inside, the boys changed the radio stations around. When I came out, they were arguing about which song and station it should be on. Zachary had it on the Fall Out Boy CD, and his friend had gotten upset that he'd been listening to 93.7, which is a hard rock station. His friend asked Zachary if this was all one CD, and Zachary said no, there was also the Killers on it, a mix tape. His friend got mad again, saying he can't listen to that type of music, the band "sounds" violent. Get it, Killers= violence. Sigh...
I put it on a talk radio station to stop the arguing. As I entered the complex, Zachary's friends asked me if I could change it again to some more music. Grrrr.... I then told him no, that I don't like being told what to listen to in my own car, that I don't let the kids decide for me, and so he won't either. I don't listen to anything violent or with swears, but I don't just listen to Christian music and country either. If he doesn't like it he can tell his mom. He said "Oh, you're right" and that was the end of that.
Maybe it's just me, but when my kids go over to someone's house or are in their car, I expect them to show respect and that includes not constantly asking the parents to do what they want. It's not the first time that I've had various people in my car who try to dictate my choice of music. It's very irritating, a pet peeve if you will...
