i do this too much actually. Ill edit rock, then pop, then metal, then k-pop...god it annoys my viewers LOL
I also switch anime and editing styles. Bleach, naruto...and then k-on and fooly cooly. Totally random anime like ramen fighter miku also helps xD
Editing styles are fun to mess with too. Ive edited like a girl, a boy, a mainstream anime watcher, an otaku, hell some of my editing even looks like its a porno XD
if any editor doesnt mix his shit up, he needs too RIGHT EFFING NOW.
Not only will you get more subscribers from it, but it also makes ur knowledge and enjoyment of editing become greater and also helps with broadening ur music and anime taste.
