This post will be a lot longer than it should be...
I chose Other. Short answer:

Anything set to music instantly lodges itself in my brain - which is why I learned my address as a kid by singing it when my mom had the bright idea to set it to a tune. As a result, I can't listen to most radio stations for more than a month, even intermittently. Pop music grates at my little dragon brain more than most, because it's designed to be (for the most part) simple and catchy. Same with country.
Because of all this, I'm drawn to music without lyrics (jazz, techno), music with lyrics I can't understand (Japanese, Russian, German, African), and music with "make you think" lyrics. Gothic fits the bill best on that last one, especially since they usually have complex musical themes as well.
Pandora radio is perfect for me because it draws from a wider, more varied pool than traditional radio stations, but even so I usually listen to a 'quickmix' of all or many of my stations.
I used to think that the only music I didn't like was Heavy Metal, Rap, and Country. I've revised that to say Pop, Country, and
most heavy metal, rap, and R&B, though not all. I still haven't met a country song that I could listen to for more than a minute.
