In the big picture of Iron Maiden's career I think Wasted Years is very important in that it shows that you can convince the fans with a more commercial rock song as long as you do it very well.
Why do you think that is important if I may ask?
So actually, I am saying that I am less happy with Maiden being influenced by their success.
