Crappy music? Poorly made...lots of autotune with people who CAN'T SING singing it.
Bad country music. Twangy stuff... And especially if it includes yodeling in any way or form.
Billy Ray Cyrus's stuff....sorry people but I don't like it.. at ALL.
Most hip-hop
Some rap music...ehh some of it, I like eminem but most of it I don't like.
I find music that EVERYONE likes annoying because they only play THAT song ALL THE TIME on their phones.
Everywhere you go, there is someone playing it, over and over and over again and it makes it very difficult for people who have to take the same bus as them, to not go crazy!!!
