Although Cups was released eight months ago, it has been in the top 10 of the Billboard Hot 100 chart for five weeks. It's a catchy song — and Pitch Perfect is a terrific movie! — but wtf is going on here?

Anna Kendrick Instagrammed what we were all thinking (well, if we thought about the Billboard success of Cups) (So probably not what anyone was thinking but still): "How I feel about having a song in the billboard top ten for five weeks. #ItDefiesLogic" along with this adorable video:
