The general definition of fun: Let’s go to the beach, let’s go get a wave.
Gaga’s definition of fun: Falling from a balcony while being metaphorically stabbed by hundreds of paparazzi cameras and then hanging yourself from the ceiling and bleeding to death on live TV.
Just remember that the next time you find yourself worried about Gaga making “fun music” for ARTPOP because you think “fun music” equates to generic, meaningless tunes with cheesy dubstep breakdowns.
