Well, the reason behind me doing this is because I want to see what genres people want me to make more of, or less of. I combine genres just to see what the final result becomes. I feel that combining genres and switching genres in a piece of audio makes the song feel more important to more people. One day, I might try to combine 10 genres and bash them all into one piece. Let's just wait and see.
P.S. You may as well think that the songs with my form of dubstep sound absolutely nothing like dubstep. Even I feel like this, so don't think you are on your own.
