This is one of my favorite heavy metal albums of all time. It's just a really good album, everything that one needs to be a good metal album. The only song that stops it from being a five-star album is the sort of filler 'Gangland'. But that doesn't take away the glory of songs like '22 Acacia Avenue', 'Invaders', and, of course, 'Run To The Hills', which deals with the plight of the American Indian, which is a subject rather hackneyed, but Maiden were really the first headbangers to do it. Many old adults did not like this album at the time of its release, but now, with all the death metal garabage going on, the slightly Satanic lyrics seem tame. This is one of the greatesr metal albums to be ever recorded. Everyone should appreciate it, cause no metalhead's collection is full without it.
