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.
Not hate per se, but my grandpa was very uncomfortable around any kind of “persistent noise”, be it too many people talking at once (he usually spent the most part of family reunions in the garage, tinkering with his gadgets), loud machines running for a long time (he’d rather walk a few miles than sit in a car for longer than five minutes) … or music. Then again he was a German WWII veteran who never went to therapy, so who knows what kind of memories he buried deep down … he never talked about it.
So … not exactly “hating all music” in the actual sense but I think he had a good reason to avoid it nonetheless.
