You're not the only one. I have tastes in music, even strong ones, but they don't tend to follow the way genres seem to be split at all.

Defining a genre by its characteristic instrument set, for instance, doesn't match how I tend to react to things very well, but it's a fairly popular way of separating genres, it seems. (I'm not saying I don't understand the use of that metric, it's very, well, available, in the sense of "availability heuristic". But I do not personally find it all that useful.)
