VMA performances often get neglected, it's rather unfortunate. It seems like it is just too close to actual show start to add it in. Interrupting Kanye was a huge deal and meme in 2009 and yet he never made it into the show.
I'm going to say some Harley Shake, Blurred Lines, Oz, Superman, Macklemore, Star Trek, Game of Thrones, Grumpy Cat, Hangover 3, Get Lucky, Amanda Bynes, Sharknado, Breaking Bad, Trouble-Swift. Just some guesses there.
