I've been asking myself this question and maybe some of brethren proggers did as well.

We all agree that the music that we listen to is mostly very smart. It is complex, sophisticated, intellectual. Does the fact that we listen to this music make us intellectually superior to the ones who do not? Of course, if I put the question like this it sounds very arrogant, so let me re-phrase.

Do you think there's a positive correlation between complexity of music a person likes and the IQ level of this person?

Have you came across any studies that would demonstrate it?

Knowing quite a bit about statistics I would be able to design a representative survey however the sheer effort of executing this survey would be to much for me...
