The life and trials of a growing Christian-Day Eleven

I've been thinking a lot about music lately. Mostly while at work because I'm a one man department and don't  have anybody to talk to other than the occasional nice customer. From the time I was old enough to buy my own albums I was primarily buying heavy metal and hard rock. I've heard all kinds of metal, and loved it all but my favorite was always the super hard, super evil, death metal/black metal. While at work, I'll get a song in my head which will lead to another song and then another and so on and so on, each song worse than the first. I wish I had never heard these songs because they seem to be etched in my mind and the more I try to get them out, the more they come to mind. No, I'm not crazy, no, it's not telling me to do anything ridiculous. I just know that that is not the subject matter that God wants in my heart and mind. I've tried to listen to Christian unblack metal but it seems to just lead right back to the satanic metal. When someone is "singing" in a deep, raspy demonic voice it really doesn't matter what their subject matter is, it just sounds like pure evil. I don't really know why I'm writing about this except the hope that maybe someone with a teenage child who is going to the "dark side" of music might read this and tell them about it. Satan is very real and this music praises him, and feeds him, and leads people  into his bondage, while the whole time they think they are being freed they are sinking deeper and deeper into slavery. When I realize that I'm thinking about these songs and that it's wrong I immediately start humming or whistling a hymn or I pray. That usually wipes the evil right out of my mind.
