Btw, so weird that you mention that whole vibration helping your help. I kinda recently discovered that this vibration helps me, too. I discovered by accident one day when I had an extremely bad headache, and was driving. I blasted Rage Against the Machine's "Bulls on Parade" and oddly enough, as the music was loud, and with a certain vibration to it, it really did help.
So now, I've gotten into some Dubstep, incorporated with Electro House/Dance and it seriously helps so much to get in the car and blast this stuff.
What are your fave dubstep songs?
