In this kind of music, the bass sounding good is essential, because there's really not much else. People come for the power behind it, how it sounds cool, yadda yadda yadda.
This just sounds like an animatronic raping a cheese grater, and that's hardly an exaggeration. It's not exactly nice to listen to, and while you can argue that's the point in itself, then there's no point in listening to it. Even other "deathstep" has something to draw you in and keep you listening, this doesn't. Heck, the only thing drawing people in is it has Freddy's dumb face plastered all over it.
And like the fellow below me said, it having little to no variation in both the sounds and the patterns doesn't help you out much. Everything else is passable but the actual drop and it looping over and over again. Sorry bud!
