Couldn’t resist. I know it’s overplayed, but the acoustic version with Janelle Monáe kills me every time.
Fun fact (no pun intended): I once (accidentally) annoyed the crap out of my coworkers by playing this on a loop for an entire day. To be fair, I had headphones on and didn’t realize just how loud it sounded to everyone else. To everyone at TechStars who was within earshot that day: Sorry about that.
