I listen to just about everything (my only "hell no" genre is country), but looking through my music collection, I put "Rock" as my answer on the poll. Because while I've got a little of almost everything in my collection, the majority of it is one genre of rock or another.
I used to hate country and rap but now I'm at a point where I can appreciate almost all types of music. I chose rock, but I used it as a blanket term for metal/metalcore/all those other subgenres. My top 5 favorite genres would be: 1.Metal/core/everything else 2.Jazz (especially jazz with guitars) 3.Pop 4.Funk/the groovier classic rock songs 5.Rap
I don't care about the genre. I just listen to it in Japanese. Mostly vocaloid like Hatsune Miku, Rin/Len, etc. although I do occasionally listen to J-pop and the artist Kyary Pamyu Pamyu.
I don't think there's a genre that has no songs that I enjoy. That being said I think my favourite would either be Trap/House/Dubstep (etc), or instrumental/OST based music. Basically things with minimal vocals. I do enjoy a lot of rock and metal as well though.
