If his audience primarily consists of geeks (and, with Weird Al getting his first airplay with the Doctor, I'm assuming it is) then I'd say it most certainly is outsider music.
(I'm not knocking geeks, either! In the fifth grade I almost got into a fight with another kid over who was better, Weird Al or Axl Rose. I was on Al's side, man.)
