As far as metal I extremely dislike Hatebreed, Devil Wears Prada, Volbeat, Dragonforce and Mutiny Within. Black Veil Brides and everyone of their ilk might also be one of the worst things to exist.
If we're talking non-metal then Carly Simon, Taylor Swift, Nickelback, Carly Simon, 98% of country music and Carly Simon.
