Kinda in agreement with everything on Wolf's list except:

FFX - Minor disagreement - I'd easily put Mihen Road first well ahead of Battle. Some songs are just bad and I file this under that.
FFXIII - Sunleth Waterscape, I love it.

I'm also not sure I'd say The Hunters or Kiss Me Goodbye are all that bad, although I don't know a particular song off the top of my head that is worse than them in their respective games and am too lazy to check the full soundtracks.
