"I forgot to include MEN also!
This (what i wrote) includes EVERY Gender!"
okay, sounds like we're in agreement then.

I think it really just comes down to the individual rather than a gender as a whole. Some individuals don't want to have to think about what they listen to, and some individuals *need* to think about it. I have to force myself sometimes to stop over-analyzing every little thing around me, while some people I know seem to have absolutely no concept of irony, metaphor, satire, or anything else than you have to think about. I have not noticed that any of this behaviour occurs more often in men or women, it just occurs in people. Intelligence is sometimes a factor, but not always.
Also, if you look hard enough for a pattern, you can usually find one. Add that into the mix with learned/expected/forced gender roles and we all start to look a lot more different than we actually are. Here's a thought: Maybe, just maybe, it's true that more men like Peter's music. . . and maybe it's because Peter doesn't fit the mold of "Emotionless Man," and men who feel pressure to be emotionless find comfort in seeing a successful man writing intelligent songs with emotion without looking like a wimp. On the other side of the same coin, women like his music for the same reason, because they want a strong, intelligent and emotional man, so the numbers probably still even out.
I think this applies to the music as well as lyrics, because even in songs that have little or nothing to do with "love", Peter has an incredible gift and skill for conveying emotion and mood. Moribund the Burgermeister, Intruder, The Rhythm of the Heat, Indigo, just as a tiny sampling of examples; songs like these would put across a clear feeling and atmosphere even without words.
(and does he have a brother my age?? *sigh* :-] )
