1980 - heavy metal's greatest year?

1980 was surely heavy metal's finest hour (year). My 15th year on the planet produced many of the heavy metal albums which are now regarded as the classics. Of the 28 albums listed below, I managed to get hold of 20, despite still being at school. I don't think much of my dinner money was spent on food that year!
