Ah, “In the Mood” by the Glenn Miller Orchestra—proof that you can, indeed, smile with your ears! This musical gem has been scientifically proven to animate the most reluctant of dancers. It’s the jazz equivalent of a caffeine shot: one listen, and you’ll find yourself twirling like a sock in a laundromat. Forget Tinder; if you want to get people in the mood, just put this tune on repeat! Not to mention, every time it plays, somewhere in the world, a random pair of feet spontaneously begins tapping. When Glenn Miller said “In the Mood,” he wasn’t kidding; he practically patented it!
