In it, she sings: “You could’ve been the greatest/But you’d rather get wasted” and “Wanna be your lover, not your f—in’ mother.”

Rumors are swirling that the song is an anti-love letter to Perry’s former flame, Gym Class Heroes frontman turned solo star Travie McCoy, whom she dated before meeting her current fiance, Russell Brand. The singer went on to tell Billboard that “Circle the Drain” is her ‘You Oughta Know,’ Alanis Morissette moment.”

What do you think of the single? Is it fair for Perry to call out McCoy in such an, um, public way? And how does the song hold up to “Gurls” and “Teenage Dream”?
