This list is flawed due to the fact that greatest hits albums have been included thus cancelling out actual albums that may appear below them if you know what i mean
But we can't just throw out every greatest-albums list that has a few anthologies on it; that wouldn't be fair. Ideally, every list of this type would contain only "actual" albums, but that's not going to happen. Henrik just omits the anthologies, that's all. It doesn't pay to speculate on what _might_ have been on a list.
I'm not complaining. I was just expressing my personal opinion about a certain list in an unantagonistic manner. I do not mean to castigate AM as I am an avid visitor of this site.
