its just playing over and over again. i like it.
Well done this is a pretty decent remix and it's dubstep none the less XD I would try to cut the synth's higher frequency a bit or lower their volume becuase they're tend to spike a bit sometimes which slightly ruins the song. Besides that well done dude and keep it up! XD
Please contact me if you would like to use this in a project. We can discuss the details.
