My little brother is a big Metal fan, (and I am a fan of some Metal to) but we both avioded guys we know are are really are satanic, one of the bands we thoght was being for real about being satanic was Cradle of Filth but before we knew that we both agreed that we thought the band was vary overrated (he even intruduce me to them because he thought they were the worst sounding band ever fromed) today I let him us my ladtop and I went back on and found he downloded there songs on my computer, when I cheked my history he went back to a few there web sites. To my shock I found out in the last few days that he has bin keeping secrtets about some bands he really likes from me. like little details about the bands history or real life views that hint that really mean what there saying. I even suspect that he is listing to really satanic bands. What should I do?
