Berklee Students, What's the Worst Song of All Time?

NPR's All Songs Considered took up the topic of the worst songs of all time. Rather than merely bludgeoning listeners with painful examples, they got analytical about what makes a song terrible. A key point was being subjected to excessive exposure; as a result, it was very generation-specific. All the hosts of the podcast were old enough to have endured "We Built This City" by Starship (available on CD 10258) back in its heyday. I'm old enough to not only hate Journey but to be bewildered that I still need to hate Journey in 2014.

No one on the show represented a younger generation. So my question to you, Berklee students, most of whom were born in the '90s and have listened to lots of musc, what's the worst song of all time that you've had to suffer through? Chime in with your opinions in the comments section. (The comments section is open to all, but we're particularly curious about this age group.)
