it obviously comes from being overly familiar with a genre. I look at electronic music and its subgenres and most of the time have no idea what the hell is going on or what differences I'm supposed to be noticing, but I look at black metal with its atmospheric, depressive, orthodox, and raw subgenres and they make perfect sense to me.
