It's quite clear that the musicians are interested in the complexities of the song they write, yet I suspect the fans like them for completely different reasons. For example, at a live show, the fans are greasy guys throwing up their hands saying, "Hardcore duuuude!" rather than stroking their chin and thinking, "Hmm yes. Interesting choice of time signature and use of polyrhythms, hmmm yes indeed." The disparity between the musicians and fans is really funny if you think about it.
