These results are unsurprising. But I think my tastes are pretty broad.
Rock will always be my favorite, I think, but I listen to rap, jazz, hip hop, metal, classical, electronic, ambient, blues, folk, and most of their sub-genres. And frankly, I think metal & rock should be separate. And definitely, as you mentioned, pop & rock should be separate. Why would those be lumped together? WTF?
The only real genres I don't listen to are R&B, soul & religious.
And yeah, I do listen to Steely Dan. They're great.
