If that's what their friends are talking about over the lunch table, then absolutely. Or, do you let your taste in music dictate your kids' social horizons?
So, the older generations’ complaint about popular musicians since at least Elvis’ hips.
I think your responses have made my point way more eloquently than I could do myself, so I guess I'll leave it here.
I urge you to consider that fitting into the culture isn't worth it if the culture is bad. You may not see the culture's taste in music as bad, which is fair, but I am sure in other cultures (say in highly restrictive and conservative cultures) you'd be ashamed to be culturally literate (antebellum south? Jim Crow era?).
