There could be lots of things different links you might like. e.g. "Parody of", "Live version of", "Cover of", "Remix of", "Remaster of" ...

Could just be a single field: "Related to". That could encompass all of the above. Then a new Tweak Order key could simply "find related". Sometimes it would pull up a parody, sometimes a live version, etc.

The only hard part is, as an end-user, it's up to you to make the relationship links. There's no way for Emplode to figure that stuff out on its own.
