rock/metal. all heavy metal, excluding anything with a "core" on the end. (excluding metalcore and deathcore) especially "emocore". that stuff is terrible. but i like all genres of metal and rock. my favorite genre however is progressive metal.
as for rap, i dislike most of it. like, what the forget is nicki minaj's problem? shes a loving terrible "artist" that i would probably pay $400,000 just to get her to stay the forget away from me if i ever saw her in person. but i like some underground stuff. and i love gorillaz, who sometimes use rap in their songs.
and i like some dubstep depending on the artist. however rock/metal are my favorite.
