In the sense that you will here them in decades to come. Only one that has real staying power is Single Ladies (it has the wedding game locked up).But I think Katy Perry wins in terms of impactful pop songs (i.e. number of songs that reached a real wide audience for a relatively long time).Beyonce: 2 Single LadiesIrreplaceableKaty Perry: 3I Kissed a GirlTeenage DreamFireworkGaga: 2Poker FaceBorn This Way
