bratsche, it could just be that people that are fanatical to a type of music (or a specific band) are fun to tweak. (and in my experience, exposure to music breeds appreciation, and exposure to fanatics breeds contempt.)
there's also a lot to be said about the effect of peer groups on musical tastes, of course. (in both directions. there's a herd of people who are fanatical about britney spears music, and the corresponding anti-britney herd. it's barely about the music in both herds, and they're both annoying.)
(what's this got to do with open-source? s/music(al)?/software/; s/band/vendor or license/; s/britney( spears)?/microsoft/.)
