Best Heavy Metal Band of all time. (Do people still listen to metal?)

Steel is a heavy metal, so i'd nominate Steel Panther. If we're limited to the original list, it's Judas Priest. Honorable mentions to Iron Maiden & Black Sabbath, even though I'm not fond of either. Credit due where it's earned though,

I'll 2nd the Scorpions, nominated by Plow. That's my choice!
