Acoustic Rock. I have to listen to it all day in my dad's car, most uninspiring and dullest music ever recorded. Also Grind core/death metal are the worst genres of music ever thought of by anyone. They are just screaming; squealing and grunting to non rhythmic music.
What about you?
I'm pretty much good with any genre, because I'm unique like that, I'll listen to anything except Hannah Montana and Jonas Brothers! There not even music!
