Clear-cut winner here with Blackbird, as it's also my favorite AB song and my declarative favorite song of all time.
Then there is a hang-up between Down To My Last and This Side of Fate.
I mentioned in another thread that Down To My Last is the perfect kind of song: not only a good verse and chorus style (with that splendid vocal Myles gives), but also a pre-chorus that is good enough on its own to be a song's chorus, and then BAM! there is still a real chorus thereafter. I also mentioned my favorite Breaking Benjamin song, Breath, does the same thing for me.
This Side of Fate is very neat and one of the epics, again slightly damaged by its own mixing and further worsened by repetitive lyrics with an anticlimactic chorus (but a nice solo to finish it off). I'm torn between the two as they are starkly different songs, but I think I'll give the edge to Down To My Last for its completeness and good sound.
There is a lot of good in I Know It Hurts. I don't know how someone can't like this song, even as a non-rock head. It just feels very accessible, even in its "filler-like" element. It's pretty high up on my list, though not a Top 15 favorite or anything.
The Bitter End is good, but I haven't liked their newer ballads after All Ends Well. Even that one has just a couple of trouble spots, as they inject one too many heavy elements into it and don't just let it be.
I'm not a fan of Waters Rising, though it was a standout in the RAH concert disc as Mark's vocals took to a newer height for me. I'll give it an honorable mention for that.
