Here's some feedback.
It's 4-5 minutes of nothing much happening. I wouldn't listen to this. The balance is horrible too, the bass synth completely overpowers everything and there's too much going on there at stages. I'd consider trying to add some kind of break in the piece and a more regular dubstep beat since the current one is pretty much non-existant.
Unmastered uncompleted track.
It's a whole bunch of nothing because it's a rap beat.
When you gonna figure that out?
