Sage advice there alexnoe, sage advice. I employed that tactic, (ignoring him) and it did work, but I was still rather annoyed at him. Well, to be 100% truthful, I used to listen to music made by Christian groups, so I still have some of those CDs which I frequently listen to. Its still as heavy as my current selection of metal, and I played that. Its still evil. :a So I then gave him the lyric booklet. And he shut up. 
@Flying Dutchman - Well, with most sub-genres of metal, the lyrics are not really understandable (unles you have an ear for them). So for the sake of the post, I was just talking about the music itself.
@kwkard - I realise that I probably have been desensitized, but thats ok with me. I know right from wrong. I believe that I control myself. I mean, I like Cradle Of Filth, some of their video clips really distrurbed me. But their music has rubbed off on me. Now they are one of my favourite groups
And their video clips are pretty cool.
What I didnt mention was the fact that I was playing it in my own room, when he came in to inspect my CDs then listen to some of whats on my PC. I mean its my damn room, my damn music.
I didnt tie him in a chair and make him listen to “Kumbaya My Lord” (Cradle Of Filth would be my torture tool of choice.) for 10 days straight. (Nice example there Mr. Belvedere, I hope I never piss you off ;))
