haha, it's funny though, cause so much of that stuff that you're mentioning, these trends, aren't musically based at all, they're like catch phrases or, basically whatever's considered to be "cool to say" nowadays...

every one of fear factory's songs(i can't stand the band, but they have amazing double bass action)will have either a synthesized keyboard or an insanly fast palm muted guitar/double bass breakdown..sooo played out..and then their chorus will consist of monistary/munk like singing, while the verse is rough sung uncreative lyrics

DMX will kill at least 5 people in each song, and, will bark profusely
