Cover art for Prove Me Wrong lyrics by Mindless Self Indulgence

The song likely has a very specific meaning for Jimmy and his wife, as has been alluded to, but I don't think many artists would go and make music talking specifically about their lives, at least not music they publish. It has a much more general meaning as well: it describes love from an extremely cynical, yet cautiously optimistic point of view. I find it interesting that people think this doesn't sound like their other stuff; while it certainly is unique, I can't think of an MSI song that couldn't be described that way. They don't have a "sound," because they always revise their style and experiment with new ideas. When one looks at the lyrics and tries to disconnect from the personal life of the person who wrote them, they can see that this song embodies the overall theme of "Mindless Self Indulgence" as well as any song they've made to date.

Granted, that's a bit esoteric, and I'm not saying there isn't an undercurrent of Jimmy's real life in the song, but I think the current analysis of the lyrics focuses more on specifics than it does general themes, and we're really missing half the equation when that happens.
