I agree that 'Beautiful Liar' is that iconic, but Beyonce has many iconic songs in her catalogue than any bitch in the game! Crazy In Love- Iconic! Baby Boy- Iconic! Speechless- Iconic! Irreplaceable- Iconic! Deja-Vu- Iconic! Listen- Iconic! Single Ladies- Iconic! Not to mention the entire Destiny's Child back catalogue!! Need I go on? Katy Perry needs to take a seat and retire, your music sucks!
