I second INTP, I can listen to anything pretty much, if it's good it's good, so I can like an individual song but hate everything else that artist releases. Though I do have my favourite genres in general, and least favourite. My favourite are probably Pop, Pop Punk, Alt Rock, Trip-hop, 50s Jazz. My least favourite are probably RnB (idk I find most of it so boring), Classical, Hip-hop, Rap, Screamo (I used to think all metal was screamo but I actually like metal when there's no screaming, or very little). Though I have liked occasional songs/artists from any of those genres of course, and I like stuff influenced by these genres.
