... Or perhaps I should've said “Quick Thought About My Lack of Musical Preference,” because I (have been known to) like a little bit of everything.
It just occurred to me that this might be because I have a relatively strong classical music theory background. When I listen to a random song, I can almost automatically pick up the theoretical elements of the song, like chord progression, contrapuntal relationships between parts, rhythmic variations and such. And the thing is, the classical western music forms the direct and indirect basis of so many different musical genres these days; to some degree, each of these genres has elements of good ol' classical music theories. I guess these elements make me feel comfortable when I listen to that genre; in other words, the elements facilitate genres that I'm not (yet) used to.
That's a pretty nifty property, I must say.
