We R Who We R [SEP] Introduction
"We R Who We R" is a song by American singer Kesha from her first extended play (EP), "Cannibal" (2010). The song was released as the EP's lead single on October 22, 2010. It was written by Kesha, with Jacob Kasher Hindlin, Dr. Luke, Benny Blanco and Ammo. Production of the song was completed by Dr. Luke, Blanco, and Ammo. In the wake of news that bullying and harassment had led to multiple suicides of gay youth, Kesha wrote the song in hopes that it would become a pride anthem. The song is intended to inspire people to be themselves, and as a celebration of anyone deemed quirky or eccentric.
