My W and I used to laugh about "Lips of An Angel," calling it the "A-Hole Song"...how ironic that she ended up in the same situation as the narrator. :P
I really got into B.B. King during my sitch. Seems like every other song of his is about a bad break-up or a cheating lover, or both. Yet he never wallows in his pain -- he just expresses it in that soulful voice of his. He's in his eighties and he can still rock the house.
