I... wouldn't use vengeance samples... they suck, and they make you look like an amateur who doesn't know how to make music. Also, if you are going to use samples, god damn, toss a link or give some credit to the actual creators.
at least it was my VERY FIRST dubstep song, at least i tried and yes i am an amateur in dubstep AND BY THE WAY, the samples belong to me, i give credit to myself because i made them and 1 used them
