"Diabolic Music" That I Love

My dad gets really creeped out when I listen to music from a certain CD I have called: Music From and Inspired by Saw IV. I haven't even seen the first Saw movie, let alone Saw IV. I just randomly have the music from it. He calls it 'diabolic music' and says "I don't think that's good for you...", as if music has the ability to affect my health. I think I'll be fine, Dad, really. Just saying.
