Honestly, and embarrassingly, I find it sort of catchy. The girl's voice is terrible, even through an auto-tune filter, and the lyrics are laughably bad...but if you strip that all away it's not the worst song ever.
It's in the edit because the whole scene makes me laugh. I won't spoil it for you any further, but I think it works. And I get to force people to hear more than 15 seconds ;-)
