The bands I liked weren't getting on MTV, but for me the classic soundtrack for a D&D game will always be early Black Sabbath. Still remember hearing Ozzie scream "Please God Help Me" for the first time while rolling up "The Gnome Ranger" in one of the first campaigns I got to play in.
In my First Edition Pantheon, The Electric was a major God. Another was "The Wizard." Both came with musical accompanyment. I had one NPC, a Red Dragon who was good (the cliche moral switch, I know) who always brought a terrible noise with him. He had the ability to project music, and it was always Heavy metal or Hard rock. We figured most characters from the day would have found it anything but musical, but of course our characters (the cool crowd) liked it. So, they heard what we heard on the stereo while playing.
