The one Paramore song my mom hates. Not to be confused with the Guns N' Roses song of the same name.
Like most of Paramore's songs, it's their usual, catchy pop-punk tone, although they seemed to have left pop-punk for more of a Beach Boys-esque power pop tone. They also seemed to have incorporated elements of funk rock, new wave, soul, and new jack swing. But, of course, they are still the alternative rock band we know.
The music video for Ain't It Fun contains Paramore--during the time Zac was still absent but still had Jeremy--trying to break world records, such as the band smashing clocks with guitars, them breaking the highest amount of discs within a minute, frontwoman Hayley Williams doing seven cartwheels while wearing boots within 20 seconds, and more.
