can't get into any kind of harsh gutteral vocal metal at all -- a few screams and the like are fine, but if that's the normal singing voice for most of the song, I hate it utterly
there are a bunch of bands where I absolutely adore the guitars and the drum work and the energy, but I think the singer is pure shit
entire subgenres of metal where the above description holds true for me

a lot of people get told about breakcore and hate it and it turns out that what they actually wanted to hear was jungle
just something smoother, less "random", and more danceable
