My mum used to say non-confrontational things like "I don't hate it but I don't need to listen to it." And with KISS it was always "I don't mind the music but I don't want to look at them!" My dad only ever said "turn that shit down", but it wasn't a put down, it was because he was trying to do something, he never really said anything for or against my music. Things changed a little in 86 when I introduced him to Jump and Dreams, and he promptly started using bits and pieces of those songs plus a few others for the videos he was making.
