wait wait wait

maybe i'm just losing my mind because time has all collapsed but was the wave of a song titled Peaches being popular the Jack Black song or the Bieber song or both

i cannot stress enough how not plugged into mainstream music i am that this is a question i am asking, because neither were That Good it seems (i dunno, they're aggressively Fine maybe?) but i saw so much posting about SOME song with that title and just assumed it was the Jack Black one because i completely missed the other existed, but maybe i'm mixing this all up in time, or........
