Annoyingly I can't embed these, but are the clips to PCD's I Hate This Part and Backstreet Boys' Incomplete not eerily similar? Key moments are Backstreet Boys' cutting to images of someone alone in the ocean as they sing 'in an ocean all alone', and at 1.52 minutes in I Hate This Part where PCD seamlessly insert a dance sequence into their ballad, presumably to give the (non-singing) girls something to do.
