Just about anything from the "Dead Man Walking" soundtrack would fit.

"Prodigal Son" by Sam Amidon is a really wonderful and haunting folk song about admitting guilt and the resulting forgiveness.

Yesterday morning I was making breakfast, cleaning the kitchen, and listening to the Rolling Stones' Beggar's Banquet, one of my favorite of their albums (includes "Sympathy for the Devil," "Street Fightin Man," etc.). This record has a great rendition of the story of the prodigal son, a biblical parable with a message that I have never appreciated, until yesterday.

The worst song ever written from point of view of both words and performance: Nancy Sinatra singing "These Boots Are Made for Walking." I wish I was joking....

Personally, I find that while forgiveness is so difficult, the act of revenge usually brings me back to... forgiveness. In moments of forgiveness, I find myself surrounded by the comforting tones of Moonlight Sonata: the repetition brings dark tones, but the higher accents leave a sense of neutrality. I am left with a piece that saturates my anger and brings light to the next breathing moment.

In angered passion, I find the eccentric sounds of Nine Inch Nails' album "Only", specifically "Why do you get all the love in the world" to be a track that, through sound, helps amplify and subdue any emotions of anger or revenge. I can live out the moment during the span of this song and by the end, I am completely through the range of emotion: revenge only begins another cycle for anger.

Patti Smith has a song called "Revenge," and "A Quick One (While He's Away)" by The Who ends with a chorus of "You are forgiven," but I can't think of any single song that features both revenge and forgiveness ("I'll have my revenge, but I forgive you"?).

MUST include Alanis Morrisette's "You Oughtta Know." Very angry, very cathartic. For months after I was betrayed by my (now ex) husband, I played this repeatedly in my car while driving and shouting the lyrics. I'm much better now. :-)
