Voting rules: Choose the song you think is the most popular!
This is a community-based ranking of the most popular Katy Perry song. We do our best to provide fair voting, but it is not intended to be exhaustive. So if you notice something or your favorite song is missing from the list, feel free to help us improve the ranking.
A participant may cast an up or down vote for each song once every 24 hours. The rank of each song is then calculated from the weighted sum of all up and down votes.
