My parents fiugred that the music I listened to, was just that, music. They were wise enough to realize that my great grandparents hated my grandparents music, my grandparents hated their music, that they were going to hate my music, and now I hate most of my kids music.
They never once banned me from any particular music, some of it they didn't want played loud enough where they had to listen to it also, but never was any group banned. So I grew up rocking out to AC/DC, KISS, Black Sabbath, Iron Maiden, Icicle Works, Duran Duran, The Thompson Twins, Rush, Metallica, Wasp, Krokus, Helix, etc.
I have also told my kidlets (12 y.o. girl and 10 y.o. boy) basically the same thing...that there are certain types of music that I don't want to hear in my home, they can listen to it, I just don't want to listen to it also, so if they're going to listen to it, they'd be wise to either keep the volume down, or use headphones (they don't know it, but they're learning to respect others also
). I won't specifically ban any particular artists or groups.
