Okay so , ive been working on a new dubstep song for like the past hour and did like somesort of a middle part of the song or you could

say its a build up to the best part of the song.

So i want you to listen to it and tell me what is missing ! or what needs to be improved

I was thinking of putting some melody in there or some vocals.
