Thats a good explanation.
I'm more into progressive rock, and think of Maiden as such. Kind of prog metal I guess. Metallica reminds me of high school which is cool, but they tend to come off to me as American white trash, where Iron Maiden comes off to me as British intellectual music. Metallica reminds me of the late 80s and early 90s when it was cool to have a comb in the back pocket and wear Metal Up Your Ass Shirts and smoke lots of crappy mexican buds and be like "Woah Fade to Black is so cool, man!"
I like Dio a lot. My favorite Sabbath album is Heaven and Hell. Besides Dio, Metallica and Maiden, I don't think there is any Metal band I really like. So I guess I'm not a real hesher. I kind of like Queensryche and Dream Theatre and some others, but not enough to really care about. I just love fuckin Iron Maiden! A total anomaly in my book! They transcend any genre.
