Lyrics to Perry's song
Circle the Drain
include: "Thought I was the exception/ I could rewrite your addiction/ You could have been the greatest/ But you'd rather get wasted/ You fall asleep during foreplay/ cause the pills you take are more your forté/ I'm not sticking around to watch you go down/ Wanna be your lover/ Not your (bleep)ing mother."
Perry continues: "You think you're so rock and roll/ But you're really just a joke/ Had the world in the palm of your hand/ But you (bleep)ing choked."
"It's kind of like my 'You Oughta Know,' Alanis Morissette moment." the New York Post quoted Perry as telling Billboard magazine.
