I listen to a variety of music, mostly encompassed by the "Rock" genre. I love classic rock, hard rock, soft rock, grunge, hair metal, punk rock, pop punk, pop rock, heavy metal, death metal, metalcore, deathcore, screamo, emo rock, punk, hardcore, post hardcore, djent metal, indie rock, progressive rock, nu metal, There is very little that is considered punk/metal/rock that I dislike. I mainly just hate modern radio rock, i.e. Nickelback, Disturbed, Five Finger Death Punch, etc. I don't dislike it because it's on the radio, I just don't like and it also happens to be popular on the radio.
I also like some rap, a tiny bit of country, some pop, and classical.
If there is one genre of music that I absolutely hate, it is dubstep.
I would say I mostly like to listen to actual hardcore. Not what many people would call screamo or death metal or the band Disturbed, etc (although I do like screamo and death metal). Actual hardcore meaning heavy music with a lot of punk influence, a DIY outlook, and a violent/negative attitude toward society. If anyone is interested, I recommend bands like Rotting Out, No Warning, Madball, Hatebreed, or Terror.
