Dub-step isn't my area of expertise or interest, but I still somewhat enjoyed this piece.
The opening and sub effects were nice, but after the 01:00 mark, I 'felt' the melody simplify and lose traction, despite the catchy 'fun-kun-dum-sta' (???). That break would've been nice after about three or four minutes of dub, but I felt that it was too short to 'get into' and, thereafter, need a rest.
T's called "trap" mate. This isn't dubstep :p Thanks for the feedback though!
Please contact me if you would like to use this in a project. We can discuss the details.
