I don't understand your hatred of Burden. Quite honestly, it's the best prog-rock song they've composed since Windowpane. It completely wipes the floor with all the filler shit on GR and a majority of the songs on Damnation, and is quite enjoyable with numerous repeat plays much like Harvest. I'd prefer to hear something like Burden over Atonement, Isolation Years, and Hours of Wealth. Let's not forget this is arguably Mike's best clean vocal performance ever, in which he used a completely different vocal style and nailed it.
As for the best song on Watershed, the answer is clearly Hessian Peel. A prototypical Opeth song encompassing everything they do best.
