I would think that there are less of these sorts of songs as there are far fewer sweet break-ups than acrimonious ones.

I know precious few people who feel close to their exes. I know a few who are amicable, but usually that is because the one being dumped has the skills of a professional diplomat, and stuffs the desire to see the others head on a pike...but still, this is usually a strained truce, at least to start. I know *far* more folks who ended badly, and now (at least one of them) wants nothing to do with the other.

A case, I would think, of art mirroring life...
