Not bad, I really liked the horns in the background. Gave it a nice feel. Drop wasn't bad either. By the way, where did you get the "drop the bass" sample from? It sounds like the one in Cinema.
If you search for "skrillex rasta samples" on google, you'll find a youtube video. Youtube to mp3 and you're golden!
Not bad, needs work, also need's a much larger back beat, it also needs a much faster beat to be concidered a Dubstep song. We'll see in the full version.
Be sure to check out the full version on my soundcloud! The drop explodes and the beat speeds up, so hopefully you'll like it!
