I posted here a month ago or something and it was about every Katy track i love flopped and every Katy track i hate smashed
Roar: i hated this song but it smashed
Unconditionally: I was in love with this song but it flopped
Dark Horse: hated this more than all of her worst singles together, but smashed
Birthday: another perfect track that flopped
If this **** goes on Legendary lovers, Walking on air and This is how we do will turn into Legendary flop, Walking on flop and This is how we flop
