Mixing "Post-Dubstep" is what I love doing since someone mentioned it a couple months ago either here or on DSF. I explored it immediately and now I'm addicted to it. But it's not post dubstep, future garage, or whatever some people want to call it. It's just a version dubstep that's different. Some artists take influences from R&B, juke, or even techno and mend them with dubstep. Don't go around saying you mix post dubstep... it's not right. Also it's not all 130. I've seen songs from 125-142 BPM.
This is the song of the summer for me:
