As you say, someone predisposed to do themselves harm is more likely to be triggered by LIFE events than music. Not defending that song in the slightest, but I’m not shocked not appalled by it. I don’t care for the death metal, headbanger stuff, don’t listen to it. None of my kids are either but I don’t censor their music. We talk often about all kinds of things, politics, morals etc current events. If they were seriously depressed and contemplating driving off a bridge I am pretty sure I’d have indications. People who worry about their kids being influenced by music would be better served by getting closer, emotionally speaking, to their kids and being tuned in to what they are thinking and worrying about. I’m very comfortable with the relationship I have with my kids, I know when they’re depressed etc.
My daughter and I do share most of our musical taste-only difference is she doesn’t like AC/DC or angry/heavy metal, and I’m not into Green Day, bubblegum pop and that whiny Seattle stuff. She did go to an AC/DC concert with MrT5 and I about 6 years ago, but she looked appalled the whole time, and said she was sure all those people our age at the concert were somehow warped long ago.
That said, the child is apparently properly brought up, unaffected by the music she listened to-married, just got her masters, off with her husband where he is working in SC, etc.
