Maybe I'm a bit biased about Wasted Years, but it's my all time favourite Iron Maiden song, so I can't do anything about it. And it has a special place in my heart. I had a relationship for 3 years with a girl, who lived around 3 hours of train ride from where I live. The verses of the song always brings me back to those long rides, looking out of the window of the train, watching the cities go by in the night, thinking of my love, and feeling pain, and sadness, that I will have to wait 1-2 weeks to see her again. Sadly we are not together anymore, but I miss her to this day, even years later, and Wasted Years always brings me back to those long train rides when I traveled to her. I always play it with my band, even if we have little time, and even if I have to sacrifice one of our original songs for it. It's just feels right.
