I never said anything was "needed." I said generally. And yes, it is true to say that. Most dubstep has a bass drop. Most D&B has a bass drop for that matter. The general structure of the song is intro, main section, mid section, second main section, and outro, with both main sections including a bass drop. And wobble bass, again, is generally incorporated with dubstep. But you yourself pointed out that genres don't matter. So why care when something you call dubstep isn't what mainstream dubstep embodies? Both are correct since Dub emphasizes drum and bass and step refers to the UK Garage roots. Your dubstep includes that as does the modern day mainstream Skrillex stuff. I know perfectly well what I'm talking about, and I don't let my bias towards one side of the genre taint my view of it either, since neither side appeals to me.

Others things to consider:

• "Use Somebody" by the Kings of Leon is 140 bpm too. Is that dubstep?

• Post-dub or post-dubstep is often defined as the combination of dub, UK garage, ambient aspects, and early 2000s R&B, a category which James Blake falls under.

• I am not really a clown
