I would like to add myself to the already rather impressive list of people who hate ska.
Also: Basically every "indie" band from Germany right now. Jesus Christ, do I ever hate Wir Sind Helden. And gangsta rap from Germany. I'm sorry guys, but it doesn't work.
And how could I forget people who cram their religious beliefs into most of their lyrics, no matter the genre or the religion (and in this case, I consider atheism a religion as well).
And finally all those bands who gave what emo once was a bad name. And it all started with Texas Is The Reason and Sunny Day Real Estate. Goddamn.
