That day and age seems to have faded, but not without the occasional fun track popping up. Case and point: Juicy J + Passion Pit. And it's quite official mind you: Passion Pit themselves uploaded this track to Soundcloud.
The pairing goes together quite well, though I find it slightly strange that at about 1/3rd through the track it's all but over, giving way to pure Passion Pit. I'll let that slide, though.
