Chase and Status
Skream (Same as The Widdler)
These are artists. Listen to them and stop searching "dubstep" on YouTube.
And your video fails. Learn to embed YT to MPGH.
Just search Rusko or Nero on Pandora and their stations plays tons of good dub. Or go to di.fm and listen to their dubstep channel. They also have an Android app which includes many good stations. I still prefer the dubstep, dnb, and chiptunes stations though.
