Watershed at number nine?
My reasoning:
Coil: If I didn't know it was Opeth, it'd be a pleasant (though not special at all) song which I'd consider to be barely on the good side of average.
Heir Apparent: A decent headbanger that appeals to my visceral, meatheady side with some enjoyable mellow bits here and there. It's about on par with the lesser tracks from the albums predating Watershed imo which is still good company considering Opeth's been my favorite band since 2004.
The Lotus Eater: A legitimately awesome track that would fit in quality-wise on any of their albums, The Mariocore middle section, though popular with fans and being generally liked by myself as well, does seem like an awkward fit for the rest of the song but I don't hold that against it since I believe if something appeals to my ears then I shouldn't be so conditional in my mindset.
Burden: Not bad at all but a tad pussy. I love every Opeth ballad prior to this and have no problem with the subdued energy level of any of their prior ballads but this one just didn't grip me. The musicianship is certainly there and it's nicely-written and executed but I get this hard-to-articulate, going-through-the-motions kind of feeling when listening to it that I don't when listening to earlier ballads. I just feel like Mike either fell in love with a boringly simplistic motif here or didn't try as hard as he usually does. The nauseacore outro is nice though.
Porcelain Heart: Good song in a new style that I actually dug for once. I think roaring would've helped it a bit though as it has some heavy parts that would've gone nicely with it.
Hessian Peel: Very enjoyable song but some parts drag a bit. 10+ minutes is no prob for an Opeth track though so I think the solution would've been to fill in the gaps a little better.
Hex Omega: There is nothing appealing about this song for me in any way whatsoever.
Conclusion: The wing tracks plus Burden could've been chopped off leaving behind a decent EP or they could've just included Derelict Herds and added a few more tracks of legit quality to round out an album of standard Opeth awesomeness but the end result we got was an album with too much dead weight that watered down the album to the point where the decent tracks couldn't even redeem it.
