I have an uncontrolable urge to headbang whenever I hear Knights of Cydonia by Muse, much in a similar way to whenever I hear Bohemian Rhapsody (see Waynes World if you need further clarification). Normal right?
Or Judas Priest... Saxon are good if you want some slightly more tongue-in-cheek stuff. I've been listening to some Polish metal today - that was pretty awesome... Muse and Queen seem a little light for headbanging - if you enjoy headbanging, I'd advise finding some true heavy metal (not Black Sabbath - they're brilliant but not so much headbanging material...).
