Songwriting Credits:
A note about songwriting credits:
As part of the required attribution and also for information purposes most songs listed on this site (including unreleased and unrecorded songs if the information is available) will now feature a list of songwriters/composers (used here as "credits"). Many sources are used to acquire this information including album information itself, ASCAP and BMI searches, wikis and other sources.
Songwriting credits for officially released albums and songs:
For officially released music listed on this site album track lists will have credits listed for all songs. To avoid duplication singles will not feature credits unless it's a song that's not on any of Katy's albums. (eg. "Rise"). If a song appeared on more than one album the credits will appear for the album the song was originally released on . For Katy's officially released covers and collaborations with other artists the credits will appear with those songs/singles only even if they appear on certain editions of Katy's albums.
Katy Perry writes and registers her songs at ASCAP under Katy Hudson, Katheryn Elizabeth Hudson and Katy Perry.
