:D 80`s style Power Metal, [Priest, Maiden, Motorhead etc] all had songs about many different subjects. This started to change with Queensryche/Manowar who started to write entire albums about one subject, not necessarily concept albums but all about one subject. At some point power metal music will return to the original 80`s idea of songs about many different subjects. & will then loose alot of the Cheese overtones !!!
