I'm not saying particular genres, we all have our less desired musical genres, I mean music in general.
When I was a child I was very confident to say that I hated music, all kinds, and my cousin used to say that was not possible.
Turns out he was right, and I only hated the teenage music my sister from the 90s used to listen to.
Secretly I enjoyed soundtracks and OSTs from several media, such as animes (digimon openings and battle themes for example) and some TV shows or even videogames.
Then my taste "evolved" and pretty much stayed at rock, heavy metal and alike.
So that little memory lane inspired me to ask about this.
I don't think it's really possible to simply hate music. You might hate songs, or bands, or genres or styles; and those may be extremely hard to get away from making it seem like you hate all music. But human brains generally like musical form to some degree. It helps in learning and memorization and all sorts of other things.
