The only reason I don't like dubstep is that the music is so overwhelming that any vocals put in it would probably just sound bad, and the fact I don't like a lot of music without vocals, though it is good when done right.
I like some rap, but usually it's R&B or something.
I like rock too, but not the hardcore stuff. Like I said, I like some lyrics that I can understand, and especially if they sound nice and all that stuff.
