It's an interesting list. I don't think Procession or especially Crypt Sermon belong anywhere near the top 25 of doom metal, and there are a few somewhat weaker choices like Mael Mórdha or Suffer No Guilt. I appreciated the curveballs like Spiritus Mortis, Forsaken, Mercy and the Saint Vitus album he chose was a nice touch.
Far from what I'd call a definitive "of all time" doom metal list though.
