Another tough one but I'm going to follow my gut and choose "Cradle to the Grave". The entire song is just so beautiful. Somber yet powerful. I'm all for the overwrought melodrama mentioned above.
"Broken Wings" would be a close second. My mind again goes back to the ODR previews that were released on AB's website leading up to the album's release. I remember it included a bit of the verse, whose dark sound I immediately loved, but then the brighter sounding chorus hit and blew me away. I had a tough time rating CttG above BW but in hindsight, BW is just a tad straightforward to make first place. Still, it will always have a special place in my heart.
The next few are difficult to rank against each other as well but I'll go with "Take The Crown" third. Its riffs and verse melody are very strong, though the first part of the bridge is a letdown for me.
In fourth place I'd put "Peace Is Broken". A massively underappreciated song full of awesome riffs and a forceful bridge.
"Before Tomorrow Comes" takes fifth place for me. It just never clicked as one of my favorites, although I recognize it's a positive and uplifting song full of great melodies, and special mention to Mark's "wah" backing vocals. A great inclusion in any live set as well.
"Make It Right" is a distant last place for me. Some of AB's weakest melodies IMO.
