Cool to get some pretty solid scores on my Watershed picks! I kind of agree that the end of The Lotus Eater is not as strong as the beginning. Overall I think a downside of a lot of the longer metal Opeth songs is that they can be uneven, having really good sections mixed in with sections that are merely okay. Heir Apparent is one of the chief exceptions to that IMO, where the whole thing is good, so I'm happy with the 8.4
The Funeral Portrait as the top song on Blackwater Park (granted you did not get Patterns in the Ivy) is such an uncommon opinion, but it's one I low-key kind of agree with. At least, for me, it would be between Funeral Portrait and the title track.
Just sent Porcupine Tree's best song even though it's not intuitively one to send here.
