What I do is really simple - I take few tracks and blend them together. I always try to mix some melodic parts with some medium heavy dubstep drops. Im not the biggest fan of hardcore dubstep, however i like to balance out harsh bassy sounds with female voice and some melodic progressions, and you will find most of the tracks i select for my sets are like that. So sorry guys, no borgore here (respect for him), occasionally noisia and skrillex but usually it will be something lighter. When i mix i focus on blending the tracks as much as possible, than i work on some effects that may fit to particular part of the certain song. I moved from long mixes to rather short mixes but kept same amount of tracks used within the mix. I think its better for the listener, long mixes tend to be boring in my opinion and make your ears tired. I also like to mix in some DnB. 4 more latest dubstep check out UKF Dubstep or Bass Heavy Music - more mixes can be found at The Best Dubstep Mixes
